Account suspended for no reason

My Telkom mobile service has been suspended for a week now with no reason and no communication. I called Telkom call centre on the 13th of December and was told there is no reason my account should be suspended and my service will resume during the course of the day, it is 6 days later and my account is still locked. A Telkom debit order went off on the 26th of November and I have not exceeded my credit limit EVER. I went in to a physical Telkom store at Menlyn Mall where I was told they can't resume my service and I have to call the call centre again? But no one seems to be able to help??? I had to purchase a prepaid sim card just so that I could make calls and send messages. Telkom your service is horrible and your call centre lie to customers to get them off the call. I have diligently been paying for a contract service from Telkom for years and this is how you treat your customers? Please resume my service.
