MTN totally useless once again

On 29th June I went into MTN Nicolway Bryanston where you were again offline to terminate the data portion of my contract which I was informed I could do so immediately.<br> <br> Since then I have cancelled data in store, online, by email and by phone - what more do you want?<br> <br> I have sent numerous emails to which you respond that you have escalated the problem to the relevant department <br> Yet I am still being billed for recurring data and I am buying data yet you bill me at out of bundle rates - I don't want to be billed for data AT ALL<br> <br> You still have not resolved or given me feedback <br> My contract is being cancelled on 4th November and I can't wait to move to anyone other than MTN
