Tired of my terrible voice service!

[tvandyck7]

I have been dealing with background noise issues for a while now. I have called VZW several times about the issue and they always just offer me a replacement phone. I don't want a replacement phone, I want the voice signal to be fixed.
I randomly get a squealing sound in the background that drives me insane. My 1x signal is never over 2 bars at best. Sometimes I get this noise, and sometimes I don't. Occasionally it will show up in the middle of a call. My other VZW line works flawlessly everytime so I don't really think it's the service.
They are offering me a brand new Droid now, but like I said before, I don't want it if it isn't going to fix the problem. They are unable to open a trouble ticket because of my location. What's the deal? Is anyone else experiencing this?
