Telkom Wrong Billing/ITC updates

Good Afternoon,<br> <br> 2 years ago I approached Telkom for their internet services, and I was informed that in order for me to get the service i need to pay the amount of R795.00 because my credit score was not good. I have contacted them 3 times already with no luck they sending me to all the departments(i,e. Sales and Billing) and every service consultant i get they say they will log a dispute but all those dispute are not resolved. when I check my credit report it shows that I am in 4 months arrears and this is really affecting me negatively I tried so many time to get Telkom fix this but no luck. I really need help.<br> <br> Thank you
