DSTV (MultiChoice) - poor administration

I was given an incorrect reference number to do a EFT payment. The reference number I was given is ********** 1 instead of ********** 1 as a result they can not link my proof of payment to my account. My service keeps getting deactivated because of this error . Iwent to the offices to have the issue resolved , was reconnected for a week , now a week later my service is deactivated again. I have called the call centre 3 times - issue can not be resolved. So what do I do? I am so frustrated.
