MTN needs to sort the call center issue ASAP

I have a contract with MTN and my account was behind payment schedule by a month and they suspended it,weeks later I received a monthly billing statement which reflected that I have a current balance of R1021.00 I paid the balance day after I tried to contact the 808 line and the line isn't working. I tried to go to MTN branches in my area and they said they cant help me only the 808 line that can help, I sent @MTNza on tweeter and I was referred to @MTNzaservices I tweeted them like several times and no luck. I seriously need my line to work I'm expecting important calls.
