Telkom The worst ever!

I took out a contract with Telkom that was on special, the uncapped 4mb ADSL line for R599. From day 1 there was issues with the service as the technician activated the service on a old line that was already in place. To make a long story short over the course of the contract I had multiple issues with intermittent internet service and billing issues. The technical service and customer service is absolutely shocking and poor as f***. To my relief my contract has one month left and then I'll be cancelling but even that has become a issue which I'll sadly explain. I was informed by Telkom that in order to cancel ill have to either go in store or call a month in advance to ensure a smooth cancellation process. I contacted Telkom and spoke to Ms Ntombi Kayose in Sales who advised me that she has processed the cancellation request which will be active 13 July 2019 reference ********** 29A and last payment due August 2019. I also queried a applicable credit reference ********** 5 due on bill dated 08.06.2019 which was not app****, to which she also confirmed a inquiry was logged reference ********** 6. Satisfied I was hoping that was the end of it however, my internet went dead two hours later and I tried everything but nothing helped so ended up calling Telkom the following day and after being posted back and forth like a idiot between technical and sales - reference ********** 58 was informed that Ms Ntombi Kayose in Sale f***ed up by cancelling my internet a month early? Like ***! My ”Tin” number 309962 was canceled and that it would have to be sorted out by her. I escalated and was told a manager would be calling me with a explanation as to how this f*** up happened and how it would be rectified because I'm aware there's charges for cancelling a contract early but was assured it can be sorted out. Saturday 15.06.19 I end up calling Telkom and speak to Mr Tony Mtumtum in sales who advised me that my internet service is cancelled and cannot be rectified reference ********** 80 - meaning Telkom f***ed up, I had to call in multiple times and got either **** to or got given false information by *********** staff (who should be packing grocery bags at shoprite) and up until now no one has contacted me to apologize for the errors and explain to me now what will happen regarding my billing. I plead with anyone reading this to stay away from Telkom - the service is worse than pathetic, the staff sound sleepy and uninterested. No one wants to accept responsibility and simply don't give a ****. If anyone at Telkom reads this please dont ask me to contact your helpline, instead contact me on ********** 628 - regards my Cancellation ref ********** 29A and billing query ref ********** 6.
