Day light *******

I would've rated 0 if it was possible. I went to Telkom in Sandton City and was advised I was billed extra on my account because I had no funds in my account. What craziness is this, so y'all wanna blame your billing system error on my account? I can prove that on the 25th my account had funds, and after doing so, I'd like to cancel all business I have with you guys, since you have breached the terms of our agreement, decided to take what we did not agree on from my account without my consent and cover it with ****. I am surely not the only client who have raised this issue and surely you guys are making a ****ing with this. Unfortunately I am not happy and want nothing to do with Telkom anymore. I'll go to other ISP,this is ****ed up and won't be ****ed like this. Please contact me so I can produce prove that I had funds on that day so you guys can return my money and cancel everything I have with you ???
