Still no further response on dispute

I complained about my dispute (Dispute number ***2) not being addressed by Telkom in a previous complaint (17:21 Thu 31 Mar) and Telkom subsequently responded with a generic response saying they are looking into the problem (***). However it has been a week and I have not received any further responses from Telkom in this regard. <br> <br> The original complaint still holds:\I sent a request on 21 Jan for cancellation of my telkom account on 21 Feb and immediately received an acknowledgement of receipt of the email. The line was subsequently cancelled on 18 Feb. Now I have recieved an account with a service charge for the full month service fee (R428.07) which they classified as a notice fee (kennisgewingskoste). This is unacceptable as I have given the full month notice they required, in writing and received acknowledgement of receipt of the notice. I have lodged a dispute with Telkom which was subsequently rejected, with absolutely no clarification on the reason for the rejection.\""
