Query: SUCKS!!! BUT customer service is amazing...

OK... sooo i just got off the house phone with t-mobile... They are sending me my 3rd V300 due to problems... My first V300 within 3 months lost all sound out of the earpiece... bassically i had to have the phone on speaker all the time... Then they sent me a second one... Within another 3 months the same thing happened to this one... THATS TWO PHONES IN A ROW THAT THE EARPIECE WENT OUT!!! BUT!!! T-mobile has replaced the phone both times with little hasle and no cost out of my pocket... A+++ for customer service!!!
