Very Poor Service from Telkom.

I am still struggling with Telkom from June last year, I have since tried cancelling my account that has so far been a years struggle! I have emailed, gone there, called and mailed again. I have since been given over to a debt collector after not receiving any assistance on a service I haven't had for months, I have reported not having service months ago and couldn't log another fault again for it was already logged. I have called and emailed numerous times for assistance to cancel the account and with no assistance eventually had to email numerous cancellation emails. I have been billed for the three months of not having a line for Telkom has not installed it yet, have also not been credited on this and was paying for a service I did not have along with needing to buy other data due to Telkom not rendering a service! I am not getting any help from any employees in Telkom and I am only being handed over to numerous agencies. I have contacted their lawyer and sent all the corresponding mails with regards to my account and was assured he would revert the query back to Telkom and they should contact me soon. this was two months ago and I am still waiting for them to contact me. Please could I get assistance for I do not know what to do or who to talk to anymore.
