Log multiple tickets, no feedback, handed me over

I've ordered a line with Telkom and the technician didn't completed the installation correctly. Log a ticket with Telkom to resolve this issue and after 2 months I gave up and cancelled the line.<br> <br> Then Telkom decided to bill me anyway, then I log a ticket at the Stellenbosch branch, the N1 City branch and with the call center to discuss this issue. These tickets where logged in Jan/Feb and I still didn't get feedback regarding the line install failure and the bill.<br> <br> Instead of contacting me via my number or email address, they decided to hand me over to the NuDebt Debt collection company. Which is harassing me daily for a small outstanding amount. They also listed me a bad payer with a Credit Bureau.<br> <br> This is unacceptable, I just wanted feedback from Telkom explaining why they billed me anyway. Instead they decided to F%%% with my credit profile and some asshole is phoning me daily for the outstanding amount.<br> <br> Is there a why I can take this matter further and for the people out there reading this. You don't need Telkom to get internet or phone line. There is other good options out there.<br>
