Unresolved Bill for 8 months

I have been trying to resolve my account problem for the past 8 months where Telkom has been charging me double. I used to have 2 accounts with Telkom and closed one. The line was cut last year September after a complain on Hello Peter but I am still getting the bill for one part of this.<br> I have gone to the branch and placed a complain but up to date no response.
