Telkom is ****!!

I had a router with Telkom for over a year, I started falling off on payments and then when I finally had little money to actually close the account, which obviously included paying a balance of eight hundred and something. After making payment I still received emails with invoices and statements and the amount had not changed, I contact them to ask what the problem Is and they say I put in the wrong reference I need to wait while they try allocate (case on case was opened and closed) this is from May, June and July.. the funds were allocated end of July meaning that the amount should have been less when the next statement came but that was not the case, I then called Telkom and asked that I want to CLOSE the account, mind you I've been asking to do this since May or earlier than that.. I am still being billed (today is the 5th of Sept) and somehow a router that was 150 from may to date is at 1500?? Please make it make sense especially for a person who has been asking to close the account, asking not to be billed cause the account is closed???

No one ever has a proper answer for the mess that is TELKOM which is why I'm bringing it. Your people don't even know where the amounts fabricated on the statement come from.
