Motorola RAZR V3m

Just got a new Razr v3m from Verizon. Had it one day. The sound did not work from the begining. I could barely hear the call confirming. I have to use the speakerphone to hear anything. Volume is almost non existant but every once in a while it returns to normal for a few seconds. I was on with Verizon for 28 minutes before they said they would send me a new one. First they wanted me to drive somewhere where the had a tech and then they wanted me to wait for a mailer send in the phone and wait for the replacement. I had to tell them how to do it.
