Sent Used & Damaged Equipment then Customer Support Said Supervisor Didn't Want to Speak With Me to Fix the Problem

I recently spent $419 on a brand new home security system from you and half of the sensors showed up in horrible condition. They were pre-owned with missing adhesive and some still had paint on them from the last owner, 4 other sensors had dead batteries, my home tower is having issues connecting to the sensors, my siren doesn't work, and the 24/7 Network monitoring I signed up for is charged to the wrong account.

The whole thing is a disaster. I just spent my entire lunch hour on the phone with customer support and the person I spoke to told me their supervisor / manager didn't want to speak to me because everyone is taking advantage of working from home and not really working.

This is completely unprofessional, I move into my home this Saturday and need to remediate the security issues immediately. Charging someone for a brand new system and sending then used and broken equipment and then not fixing it is theft in my eyes.
