I used my Upgrade to get an HTC TITAN & got a great deal at just a .01! However, I've already returned the first one and I'm about to return this replacement I received due to the call quality/people complaining about me being muffled and/or having to repeat myself 2-3 times. I don't want to get another TITAN, would love to get an LG Nitro or HTC Vivid, but can't really afford the high price tag. Anyone have any tips on how to "Work" Customer Service to convince them to give me a great deal (if not for free) on one of the other phones - since I've had so much trouble?
