paid but ac**** suspended

We have a cellphone contract with telkom mpbile which includes 2 phones, we paid but funny enough the one phone is suspended and the other one is fine.. We called the call centre numerous times since last week and all they could say was that they dont know what to do or how that can happen. How pathetic is that..?? paid on the 25th feb and even untill today no one has called or botthere to activate it. We stil cant get answeres or solution from telkom
