Telkom are theives taking advantage of people

Telkom, I am completely appalled by your "business" ethics. I have a telkom mobile account for R299. At the beginning of this year I changed banks from FNB to Standard bank. I immediately contacted all of my creditors to update my banking details. Telkom refused to take my new bank details until the account was 3 months old (the ONLY creditor with this silly rule) I then said no problem, I will EFT each month which I have been doing only to have my cellphone disconnected today. I phone 10210 to find out why, only to be told by a lady called Gugu from your mobile team that you guys have charged me R203 a month for each failed debit order. I get told that you would rather debit an empty account than debit my new account that gets my salary each month. I am now in arrears for R600? You guys are theives. This is how you treat customers who try to pay their accounts? By allowing them to go into more debt because of your outrageous ideas???
