Price lock and dsvt call center chaos

When i app**** for Price Lock the agent was very pushy as to what kind off deal I should take. After much consideration I decided to take the Price Lock for the decoder only so I would have the freedom to decide which package I have. Delivery and installation went extremely well received everything within the first week. When the first month arrived to pay, my debit order never went off I had to do a eft for the amount of R1270-00, SO QUERIED about the price explained it was prorata, totally understood that. I specifically told the agent at dstv customer care I did not agree to the R959-00 price lock could they please rectify this, the lady I spoke to her name was Didi, said she would escalate my query to the price lock department, and they would call back and fix this. Needless to say I had to phone 6 times for this matter to be escalated. No one from the price lock department contacted me as yet, beginning of the new month same scenario with regards to payment, phoned 3 times yesterday to get this sorted, no one has phoned me, I get mixed messages from customer care agents, some extremely helpful , and some very rude that does not give you the time of day. The last customer care agent informed me I have an outstanding balance of R4500-00, she could not explain why., promised her supervisor would be in contact with me. I am highly irritated about this whole situation, I need someone competent to assist me in sorting this matter out
