Cell C continues to take money from a debit order

After a burglar in December, I contacted Cell C about blacklisting my phone and cancelling my contract. On purchasing a new phone, I discovered that the contract had not been cancelled and the debit order was still being enforced. I haver tried repeatedly to get Cell C to sort out this problem and the last time I was told that my number had been permanently disabled. At no time were they ever instructed to do that. I am paying but getting no airtime in order to make phone calls. Their call centre staff tell you a different story, when they bother to contact you the people are barely understandable, the information is wrong and if one goes to a Cell C store, as I did, I was told that having sold me a new starter pack and obtained a Sim swop, I would be back on air within an hour. That was more than two months ago. Nothing has been heard of from them for more than 3 weeks. I am so sick of no service, paying! for no service and now no number. They are the most useless Cell company around. I am.unable to supply you with a movile number, as Cell C took it upon themselves to cancel it - they were NEVER TOLD TO DO THIS.
