EARLY TERMINATION

I have requested MTN more than a week ago to give me a figure to do a cancellation on my contract - they have been sending me e-mails asking information that they should have on there system - it has been going on long enough. I have not yet decided if i want to move my contract HOWEVER they want to know what they can do to keep me as a client - WELL GET YOUR CUSTOMER CARE SERVICE in line - and respond.? I CAN NOT MAKE A INFORMED DECISION IF I DO NOT HAVE THE INFO? PLEASE CAN SOMEONE ASSIST ME?
