Bad service

In September they activated my service without my consen now they telling me I am owing them September bill, I talk to 3 people already my using my airtime spend more than R100 calling them to reactivate my account because I paid this month is almost month end but my service still closed, the call center keep on telling me they will pass the credit and activate my line, they activate while I on a call with them then after few hours is disconnected, I want my money back for the month of October because I paid for the service to be activated.
