Geek Squad complaint: no way to complain about geek squad

I have had repeated problems with phone geek squad and have tried numerous times to complain without being able to reach anyone who can even take a complaint.

Most recently I asked them to help me resolve why my speakers and microphone suddenly were not working. My laptop said they weren’t installed. I asked GeekSquad to check it out, and said I thought it might have to do with a recent update. When I went to the level 2 tech, he took 5 minutes to say it was a hardware problem and there was nothing he could do. Also, I never go the survey. I spent another 10 minutes online and did a system restore back to the last restore point and presto, everything worked again.

This is the information I have about the recent service so you can check it out.
Geek Squad case ID:
Session ID: CAS-13964585-F1B5T1
Date: Date(1675656592000)

When I called back, they said I would escalate it but I never heard a word:
Escalation case ID: escalated to next higher dept
