NEVER USE MERCHANT'S TIRE !
Here is a copy of a complaint that I logged in to the tire kingdom complaint contact center. As you can see I asked for someone to contact me in reference to this overcharge and customer service issues. As of this date I have received no contact.

On Thursday evening July 08, 2010 I went to your store at 2720 Hillsborough Road in Durham, NC store # 332 to purchase 4 tires for my son's vehicle. Once there I was told that the tires I had chosen would cost $44.99 each, even though I'm aware that many of the tire shops have a basic price and an additional charge for installation no mention of any additional charges were made by the store manager when we left the car for the service. I expected the manager Mr. Greene to be more thorough in his presentation to the customer. We were told that it would be an hour and a half before the car would be ready because there was only one person available to mount the tires. We returned in an hour and a half and the car was being completed by another person who I had not seen. This young gentleman was very helpful and courteous when he returned the car to us, he even rode tested the car with my son to be sure that everything was OK. Once we received the receipt for the tires & service, I noticed that the bill had a charge for HIGH PERFORMANCE TIRE SERVICE, so I questioned the person at the counter about the charge. He immediately recognized that the charge was incorrect and told me that I would have to return tomorrow to get the refund posted to my credit card. I explained to him that since the store was open I expected to get the charge corrected then and not have to return to get this matter cleared. The young man told me that he didn't know how to make a refund to a card. So I told him to call his manager at home and have him tell him how to handle it. He called the cell phone of the manager and did not get an answer, I attempted to call the manager also from my cell phone and got no answer. Mr. Rogers who was the young man trying to help me out checked the computer to see how the tire charges populated to see if it was a computer error and it was clear that the computer charged a fee $7.00 per tire less than what was charged to me. Mr. Rogers was finally able to contact the service manager who was able to talk him through the refund process and the card refund was posted. I thanked Mr. Rogers for his assistance and appreciate your having honest persons working within your places of business.

I was prompted to write you this letter because as I was driving home Mr. Greene the store manager called my cell phone and we discussed the charges. He immediately told me that he would refund my money if I would return to the store on tomorrow. Then he told me that the computer automatically populated the charges and it was a mistake. I told him about the young man in the store checking to see if the computer was doing it and it charged the correct fee. Mr Greene then told me that Mr. Rogers had no business showing me what the computer populated. It was then that I realized that it was clear that Mr. Greene knew what he was doing by charging the higher fee. I explained to Mr. Greene that as a manager he should know his product and know that the basic tire is not a performance tire and should be aware when his charges are incorrect. He insisted that it was a computer error and that it was not his intention to overcharge me. He made too many inconsistent statements and convinced me by those statements that he was clearly aware of what he was doing. In addition when I first entered the store I observed a young lady in there very upset and stating that she was going to get the TV station reporters in there for how she was treated. At the time I didn't consider it any of my business so I didn't try to determine what her complaint was but now I feel that customer service is not a priority at this location, and contacting the TV stations is not such a bad idea. As a business man myself I understand the need to improve the bottom line and in sales you should make every effort to increase the profit margin, but I feel if you cheat the customer all your efforts fail because you have to work much harder to recover from the negative message those cheated customers carry away from your business. It is clear to me that you have a problem in that store and I hope that you will check into it before this manager destroys your customer base. I'm sure your computer system has the capability to check the to see if the there was a manual adjustment to this purchase and I would like to receive some contact from a company official about this matter. The Invoice # 40618927 is the original bill and Invoice # 40618616 is the refund, my apologies for the detailed email, however even after sleeping on this all night I am still very unhappy with the service provided by this manager Mr. Randy Greene.

I WISH I HAD READ A FEW OF THE COMPLAINTS ABOUT MERCHANTS BEFORE I PURCHASED THESE TIRES, I WILL NEVER USE THEM AGAIN AND I WILL MAKE IT MY BUSINESS TO INFORM EVERYONE I KNOW ABOUT THEIR SHADDY BUSINESS PARACTICES.
