I took my iPhone 14 Pro in for a battery replacement and the staff were all super friendly and helpful, and nothing went wrong with the repair on Geek Squad's side. I wish they would pay more attention to the types of repairs people need though - when I took my phone in the night before, they told me there was already a repair in process and I'd have to come in within the next few days. I could see this being an inconvenience for people who live further away.
I also dislike the AI call center, as it is super difficult to talk to an agent or an employee within the store and when I was able to, I was on hold for 14 minutes. The person I talked to was a bit rude as well and it seemed like I was inconveniencing him.
I recently went to Best Buy and purchased a new Samsung Galaxy S26 Ultra and a new Samsung 55" TV. I had excellent customer service in both departments. I met the Samsung representative and he was very helpful too. I am also having Best Buy employees come to my home and installing my new TV, and moving my old one to my art studio. I only had to wait 6 days for the install. If you need electronics go to Best Buy, it truly is the best buy! Lol
