Deducting R1800 via Debit Order for their mistake

So Multichoice just takes R1800 from my account, 4 days of calling and getting cut off, calling again just to get told it will take 40 days !!!! Agents can't cancel or stop the debit order, that must escalated too and will take days.<br> Never had this issue ever before, what is going on now. Spoke to a manager and she just says she needs to investigate but I can get a credit for 699 still leaving me getting billed R1100!!!!<br> <br> Very unhappy
