Bad bad service..

I went into Cresta store Telkom and app**** for data contract fine it was done e sim done approved. and was told debit for data will be done monthend together with my cellphone contract,in the middle of June I saw messages from bank that Telkom tried debiting and there were no funds then I thought to myself but this people I have been with them on my current cell phone contact for the past five years,and no debit did not get funds and now they decided to debit whenever they want,they did not call me to say we suspend your line here is the account go and pay at least,two weeks after suspension I went into Cresta store again to find out what is the problem,they called the consultant on line and she just said have money in your account and after ten days Telkom wil try debit again and she just dropped the phone just like that I am four weeks now without data and this people now will make double debit for data I never get to use really?my number is ***
