Extremely frustrating and disappointing experience with Best Buy.
I purchased a Google Nest Thermostat (4th Gen, silver), but the color didn’t match my wall, so I went to return it within 13 days. To my surprise, the store refused the return, claiming that the serial number on the thermostat didn’t match the box. They implied that I might have swapped the device at home, which is absolutely not true.
What made this worse is that they openly admitted they have no proper way to verify whether the device actually belongs to that box. So basically, I was being blamed for something I didn’t do, with no way to prove my innocence. I even purchased a protection plan, which now feels completely useless because if something goes wrong, I might not even get support due to this mismatch issue.
I visited the store on both the 13th and 14th day. On the 13th day, Devin told me the product could not be returned. After some time, another manager, Diana, came and said the system was not accepting the return at that moment and the store was closing, so she asked me to come back the next day and assured me that she would process the return.
I came back the next day as advised, but unfortunately Diana was not available at the return counter. I met Devin again, and he once again refused the return saying the product cannot be returned. This was extremely confusing and frustrating—one manager says the return will be processed, another says it cannot be returned at all. Completely inconsistent and unprofessional.
The manager handling my case, Devin, was arrogant and dismissive throughout. He didn’t listen, showed zero empathy, and kept repeating that they “cannot return the product.” This is not how you treat a genuine customer.
To prove my point, I bought another brand-new thermostat from the same store and opened it right there in front of them. Guess what? The serial numbers didn’t match on that one either. Only then did they realize the issue wasn’t on my end. But even then, there was no apology—just attitude. When I asked whose fault it was, the manager snapped back saying “don’t scream whose fault,” which was completely unprofessional.
I did nothing wrong, yet I had to go through stress, wasted time across two days, and frustration just to be heard. This kind of customer service, lack of accountability, and poor coordination between staff is unacceptable.
