Billing incompetence

DSTV's pure incompetence in its billing department continues……. DSTV auto-debits my bank account, but then doesn’t credit my subscription and shuts it down. I contact DSTV and I need to prove to them that they have deducted the money – surely, they should know they have processed the transaction??? I speak to the support team yesterday and I am told that it will take 1-2 hours to resolve. Its now the next day and still nothing has been done. I left DSTV years ago because of these billing issues and I see that they continue -is this not a failure of their financial controls??? The exact same thing is happening with a family member.
