This review is more about loyalty and good customer service than anything else after being charged a 100+% promotional interest penalty. I made a mistake, and had a promotional purchase being paid on a monthly "auto pay" from my bank. I didn't pay attention to my monthly statements, because I knew it was being paid every month ( early every month ). When I did look at recent statements, I noticed a problem. When I went back a few months, I saw where I received a $457 interest charge on a $422 remaining balance. I immediately called when I found the problem , and was told since a few months had passed there was nothing they could do now. I told them I would have paid the $422 if I would have known to avoid a 110+% interest charge. I asked if they could split it or do anything as I have been a customer for 20+ years and literally have spent in excess of $20k. The answer from Best Buy customer service & her supervisor for that type of loyalty is "I am sorry - Nothing we can do". I've learned my expensive lesson here, and will spend my money with a company that appreciates the customer. That definitely is not Best Buy.
