Price lock - incorrect billing, terrible service

If i could rate a minus I would. Since signing up for price lock my account has been debited incorrectly every month. Call center staff cannot help, the best they can do is escalate the query to some mysterious 'back-office' that apparently has no phones. Callan Esbend is a call center manager and promised to get back to me, this still has not happened two days later. I have had this from another call center team 'leader' but I did not get her name. No one is able to provide a solution. I have zero faith this will ever be resolved. I now sit with a decoder thats not installed (which is breach of contract from dstv), incorrect debiting of my account and a bunch of idiots who's only power is to 'escalate' an issue to some unknown back office. This is a proper third world we now live in. ***********, no care to look after paying customers, zero ****s given by any staff of dstv about my issue.
