MTN SOUTH AFRICA THE WORST SERVICE PROVIDER

I have made my payment on the 12th April my payments have to go off on the 15th of every month. Yesterday the 15th I receive a sms saying that my phone has been suspended. I then went into the self service site, the statement is only up to the end of March. So I called the MTN help line listened to the same boring music for 2 hours. 135 and 136 can't help me because my phone has been suspended. I sent them 2 complaints on their website which I received acknowledgement of then I mailed them from my gmail. My contract end with them this month. (Thank goodness) I haven't heard I thing from them and to make matters worse I am waiting for interviewers to call me as I am in the job market.
