Best Buy Tech support broke my home theather and wanted to charge me to fix it Richfield, Minnesota

Hello hows it going, I have the most ridiculous issue i ever faced before. I bought a home theater from Best Buy 2 years ago, which cost around 18 thousand dollars.

Today i call up Geek Squad because i had an issue with my remote, around a year ago they came to repair it and
removed the battery which for some reason i was not able to remove it myself.

Which is the reason why i called them in the first place, so i spoke to one of the techs in the repair department and she told me that my installation warranty is up but i still have a year on my repair warranty.

She told me this is not a repair related service and she cant send a tech to my home, she went on to tell me i should try and see if the blaster for my remote is unplugged or not.

I told her i have no idea what a blaster is or how to look behind my receiver which had many wires. She told me i have to do it myself and that it's okay it will be fine, so i moved the receiver myself and found nothing there
which i seen was unplugged.

About a minute later i noticed that my back speakers were not working after moving the receiver around, i told the
agent and she told me that the best she can do is charge me 99 dollars to send a tech to troubleshoot the issue.

After she made me move my receiver and mess up my speaker setup she had told me that i have to pay
to get an issue she caused fixed. I could not believe what she told me i even had to ask her a few times to repeat herself, i asked to speak to a supervisor and she told me fine and 2 minutes later the call was lost.

I call Geek Squad back and ask to speak to a supervisor and they put me on hold for 15 minutes only to transfer me to a department that is closed. I have no idea what to do, i will without a doubt never buy a product from Best Buy ever again.

I was on the phone for 2 hours and my issue was not resolved, i guess the best thing to do is BBB or Attorney
General. It's not really even about the money for me, I just cant believe how they treat a loyal customer.
