Two terrible interactions in one month. The latest involved an automatic renewal of my Office365 subscription through Best Buy. I was charged on Aug. 7, but started getting notifications in WORD that my subscription had been cancelled. After 2 1/2 hours on the phone being passed from dept. to dept, the upshot was that, as far as Best Buy was concerned, my subscription was active and that if I wanted them to investigate why Microsoft didn't reflect that, I would have to pay a one-time tech support charge of $99. I told them to cancel the subscription (I went directly through Microsoft instead). 10 days later, I didn't see a credit. Two subsequent calls to Best Buy - reps said the credit had been issued, but it would take up to 15 days to show up because my credit card company was really backed up with requests and slow to issue the credit. I called my credit card company today, and they had no record of any request being made by Best Buy for a credit.
