6 months of incorrect billing

You really do have a serious problem with your billing system. I DESPERATELY DESPERATELY DESPERATELY need to be put in contact with someone senior who can deal with the billing issues my wife and I are facing. Every rime we lodge a complaint via your call centre, an agent calls us back asking whether have received delivery of of explora decoder?! We cancelled our insurance on two decoders we previously had 6 months ago and asked to pay insurance for the explora only. This have never been actioned and I would like reimbur*****t for this. Yesterday you deducted a R1800 debit order from our bank.account instead of the normal R799 explora deal we signed up for in March...this is the 2nd time this has happened this year and I am.serious considering going to the police and opening up a ***** case against multichoice. .this is.how serious this matter has now become. I am being considerably polite in this message to multichoice given the absolute diabolical service I have experienced from you over the last 6 months. .I REALLY do urge you to assign someone senior and accountable enough to deal with this case once and for all.
