Multichoice employs idiots

I took out dstv internet at the beginning of the month, and provided multichoice with banking details to debit from. Come debit order date, they process the debit order from an account I do not use, resulting in unpaid fees being charged. I spoke to a Kgomotso, who dutifully told me that he/she is not obliged to give me their name when I asked for it because I don't know if he/she was being daft with me or is really stupid. He/she deliberately ignored my question on who is going to pay the unpaid debit order fee more than 5 times. I need multichoice to pay this fee!!!!!
