Incompentent call centre agents not giving correct information

Very unhappy customer. Phoned in to downgrade my service for the coming months. Agent advise that I need to pay R110 . I payed the R110 as advised . Last week Monday my service was disconnected. I once again phoned in agent apologize and reconnect the service without mentioning that I need to pay a R54 . On Saturday my service was again disconnected now I need to pay a R150 to connect my service . I'm been punishment for agents incompancy after I did all the effort to keep my service on . I'm still without a service double the amount that I downgraded to . I mean there was a reason why I downgraded cause I couldn't afford the compact subriction for the coming month but yet we are left with nothing!!!!!
