Best Buy review: Insignia tv replacement

We have already had a service call from Best Buy on this TV for sound issue. They updated the software and supposedly the sound issue fixed. We waited for about 3 weeks to see if this fixed the issue, but after that time it is still not working correctly. In attempting to work with Best Buy to return and replace the TV by having them credit us against the new TV, they indicated that our return time expired. The major problem is that it takes some time and use to determine whether this software update worked or not. Actually, the sound stopped working and we had to reset everything to get it back. There is some system component that is not working correctly and it appears not to be a software issue. We have a contract with Best Buy, under Geek Squad, but the still don't offer a solution that is acceptable. In the end, we will NOT buy from them anymore (we even tried to buy a freezer from them) and found that their setup fee, delivery fee and even removal of the old freezer was not competitive with Home Depot. Count us as very disappointed previous customers.
