Early debit

I started a contract with Telkom for a Huawei router and SIM last December. Initially everything went well until April this year. Their billing is an absolute nightmare. I have been in collections pretty much constantly since then despite Telkom debitting the wrong account for two months. I made a manual payment for three months now and Telkom claim that I am behind one month. I phoned the call centre last Monday and the lady that side told me she could see that my account was not in arrears but I was handed over anyway. She said she will "escalate" the matter with her manager and that I will be out of collections within two days. Two days later I phoned the call centre again only to be told that I am STILL in collections and will remain there until my "arrears" had been paid. This morning I woke up to a drained bank account because I was never taken out of collections. This is just a drop in the complaints bucket when it comes to Telkom. I initially considered moving my phone contract over to Telkom Mobile next year but after experiencing the worst customer service ever, I will no longer be moving my contract. Furthermore, I will take my business elsewhere when my contract with Telkom expire next year. That one company can inspire so much hate and incompence is beyond the pale.
