It seems simple enough. The last time I went to service my car, I had to buy a part. So I ordered the part, and prepaid for it. I was told that I would get a phone call to notify me that the part had arrived. At any rate, a month goes by and I didn't receive a call. So I took the inititive and called to find out the status. I was told my part was there, so I decided to come in next month so I can get the tires rotated etc. I didn't bring my receipt, probably because I was thinking they would be able to pull it up via my frst and last name, which they were. However, the person went in the room and stayed there for an unusual amount of time searching for my part. Then he had someone come and help.
They later came back and told me. Well the part that you ordered, was purchased by someone else. Being me, a logical person. I asked, "how can you sell a part I had already paid for?" They go into some company policy they couldn't show me anywhere, that after 30 days, they have the right to sell a part that was purchase by someone else. Then they began to ask me, so do you want to re-order it?
I suddenly realized, why some people end up getting punched, or even worst. I order a part, I paid you my money. And you sell my part I paid for, to someone else, on top of that, you didn't put in another order for a part that was paid for. And you wasted my time, to wait for me to get there so you can ask me to re-order it.
So I basically said, "Refund me back my money." They then asked for the invoice number, which as stated above I didn't have, so they said they were not able to refund me back my money unless I have the invoice. I told them that it is simple, I will chargeback this purchase, and they would be left with a 25 dollar chargeback fee as well. So who would design a system where they have to have the invoice number to grant chargebacks. Humans are fallible, they will loose things, so why would you want to make a system that would increase your chargeback percentage?
