Pathetic Telkom service

I haven't been receiving any Telkom service due to the theft of cables in my area in February. My land-line does not work since then, yet Telkom has the audacity to send me a damn invoice each month that I should pay for a service I do not even get. I have sent in a cancelation form in April and waiting for my service to be canceled this just does not happen. I havent received invoices for the past 3months and all of a sudden I get an invoice for end of July of 1400rands. This just fueled my frustration as I sent in a cancelation form months ago. So I sent them an email asking for a consultant to contact me as I can not call Telkom each time only to wait in line till my airtime reaches a zero. They respond and ask that I resend the cancelation form I do this and at the same time I tell them I refuse to pay the invoice as I haven't received the service since February. They ask I send in a another dispute last week and so I have and they yet to respond so send another email to the same thread today and they respond that I have to do the cancelation online. Pathetic!horrible service, inconsiderate towards their customers no care whatsoever. Imagine paying for a service that is unavailable to you that's roberry!
