No feedback after complain

A week after my complaint and I did not get any response from Multichoice. I informed them about the R 12026.72 deduction from my account and they did nothing. I reversed the transaction at the bank and informed them. No reaction. I requested via telephone, SMS and E-mail a statement and an Invoice to pay the outstanding (CORRECT) amount and did not got any feedback. Even the person called Elna who responded on the Hello Peter Complaint did not contact me.
