USELESS, ****PY TELKOM

I cancelled my Telkom ADSL line in October 2017. To date I am stilling receiving monthly invoices and now I have a letter stating I am going to be handed over due to non payment. This, after numerous emails and phone calls, Telkom have still not resolved the issue. I posted my complaint on social media and cannot believe the number of people in the same predicament as me! What are you going to do about this Telkom??????
