TERRIBLE CUSTOMER SERVICE

IM VERY DISPLEASED BY THE CUSTOMER SERVICE!!!! I've Called MRP over 10 times and have been put on hold for about 30-45min each time, I've sent an email with no response, next thing they going to want to deduct from my account. I have been trying to cancel my 12month contract as it has ended! I'm sick and tired of paying this contract because since I took it, it hasn't worked even once , it never has network. I REFUSE TO PAY ANOTHER CENT. I've never seen such terrible customer service.
