Progress on my ***** case

I am really fud-up with MTN. This is the response from *** is "Please note we have redirected your email to ***** teams and it them who will provides a final advise on your request, please wait for their feedback or you may follow up direct with them," and the response from '***" is as follows" "Thank you for making contact with us please dial 083 135 to report your matter to a service consultant". None of these responses are doing anything to my enormous account of R12,960.25. I want them to rectify my account and to give me feedback on how far they are with the ***** investigating but nobody gives me feedback. As it is, MTN is going to deduct the money from my account on the 28th and there is nothing that I can do. The debit order must be stopped by MTN!!!!!
