Incorect charges on account

I phoned their consultants twice already and both times I was promised a call back. I received my new DSTV decoder and was installed by one of their referred installers. All my detail was given and then the consultant spoke to the installer directly to activate the new decoder. The old decoder was never cancelled by the consultant and I was charged for 2x devices. I spoke to a consultant on the 29th and he explained to me that he is requesting a reversal on my account and will give me a call back. I also requested that they do not process the debit order but was informed it was already submitted to the bank and I should reverse the debit order and they will give me the correct amount to pay. No feedback Today I phoned in again, explained everything, promised a call back.......no feedback I need somebody to get back to me, tell me the amount was reversed, and also give me my correct amount to pay
