Help: Cutlass RS HSS (problems)

I recently bought my dream guitar Cutlass RS HSS last year for my Birthday. Initially I was over the moon about the playability and the tone. Out of all the guitars in the Platinum room this one just really came to life. It was I couldn’t get over that experience and it stayed with me for weeks until I decided I just had to have it. After several weeks of playing it I began noticed that it buzzes all over the neck. It buzzed when I first bought it but the store worker said that it was because I play to but that’s not the case at all. I said no big deal I’ll just get a setup and it should be fine. But even afterwards there was still buzzing. A few weeks later I noticed the volume know was cutting around 9-10. It eventually got so bad that the slightest touch on the knob from playing will completely wipe out the signal with a very loud pop in the middle of live performances. Today I was going to practice and now the pickups are putting out a horrific sterile plastic sound. After checking cables, pedals, and amp it is indeed the guitar itself. Within a few months this guitar has become a nightmare.I don’t want to take it to a guitar tech at GC because I don’t feel they truly care judging from past servicing. Does anyone have any advice?
