telkom mobile *********** staff, pathetic service!!!!!!!!!!!!!!!

i have never before dealt with such pathetic useless service honestly, i got a telkom mobile free me contract for 100 bucks a month over the phone. from the first month the debit order had bounced for some reason but i never recieved any message from my bank nor was their insufficient funds in my account (cmon its 100rand !!!) , so i called in and the banking account number they had on my account was not even my account number!! so i gave them the correct details and 2 different ladies confirmed my account details have been changed, and as you can guess by now, this month, AGAIN, i get a lovely sms from telkom saying my account is in arrears. what telkom mobile fails to realise is that this has a negative effect on my credit score, and as im in the process of applying for vehicle finance, this is a huge set back as the bank can see i have bounced debit orders and they have already refused me finance BECAUSE OF A TELKOM MOBILE ACCOUNT THATS IN ARREARS!!! to no fault of my own. telkom mobile really has great prices but for the service you recieve its not even worth getting an account with these people, ill rather pay that little extra with another service provider and get service FROM COMPETENT PEOPLE !!!!
