CANCELLATIONS NOT ACTIONED - WORST SUPPORT EVER

I have requested to cancel 3 lines by email to the cancellations dept on 1 Nov. After that I followed up with a call and the person told me they cant do anything as there is a 21 day turnaround time. Well I have tried the facebook method as well as the chat. I also requested the cancel on the Telkom App. No call or whatsoever. Everybody will get back to me. I spent 35 minutes on the phone today as well. You will never guess.. someone will come back to me. I got my invoice yesterday and guess what charged for all of them and they are still working. I dont know what else to do. I have app**** for adsl with Telkom begin Nov which is another disaster story. Now I can not continue with the one if the other one is not cancelled! Until today my adsl has not been completed, after 3 attempts. Maybe that is a blessing in disguise.
