billing

on the 2nd of Feb. as i wake up i tried to make a call but i was told that my numbers have been suspended, and also i cannot check my balance. i than called the contract call centre to find out why is my number suspended? i was told that is because they are still sorting out my monthly statement and that in a day or two everything will be back to normal but till this day i not received my statement for January nor any call from the centre to inform that my sim is sort. simple English ' i still cannot make called nor use my sim. i have been with mtn for 11 years and loved it but now they are letting me down. I'm looking to change my service provider.
