cant get any help

i recharged my phone with R12 airtime and it did not reflect in my account balance. i can not contact customer care because they have bared me from using that service since the time of my last complaint, since then no one was able to tell me why i was bared and what did i have to do in order to use this customer care service. if i have a problem i got to ask friends to borrow me there phones so i can call customer care.
