On Wednesday January 20, 2010, I went in to buy three slices of pizza. As far as I knew I had paid the bill for $4.01 and left the pizzeria. Then on that following Saturday January 23, I was checking my credit card online to find that my credit card had been swiped twice one for $4.01 and one for $8.01, totalling $12.01. Immediately I called the pizzeria, and spoke to the manager. The man said that if I got 3 slices of pizza, I had to pay for them even though they had forgot to charge me. I was on the phone with the man for 10 minutes. All he did was yell at the top of his lungs, ask personal questions unrelated to the matter, and say that it was his right to be able to charge me. The fact of the matter is, I was in the pizzeria for at least ten minutes after I had paid and at no time did they notice their mistake. I don't know their menu prices therefore I wouldn't catch that mistake. He didn't try to contact my credit card company to let me or the company know that he was going to make a unauthorized transaction. They can't just charge a credit card without the holder knowing it. Not only did he handle this situation in the most unprofessional way, but he showed the worst customer service I have ever seen.
