Telkom Mobile is refusing to contact me regarding a cancellation query

I have been trying to cancel my Telkom LTE account since September 2017 and have been unsuccessful due to the totally unprofessional nature of the Telkom Mobile billing department and their rude and unhelpful call centre staff. I have sent the necessary cancellation request as per Telkom's guidance and yet my account is still active and I am being billed monthly for it?

I have contacted the call centre on numerous occasions only to be told that they have been trying to contact me and yet I have received no missed calls. They repeatedly give the same excuse that they have tried to contact me but have my incorrect cellphone number even though I have given them the correct number multiple times so it is clearly a lie and a tactic being used to try and delay my cancellation request.

It is obvious that Telkom cannot compete with the low prices and great service delivery offered by Vumatel and other new entrants installing fibre connections and their ISP's such as Cool Ideas etc who offer a great customer experience. Telkom is hanging on to customers to dry bleed every last cent before they lose them as they simply cannot compete with a new market that is finally offering great service. A word of warning - avoid Telkom AT ALL COSTS they will just cause you endless months and years of frustration with poor connectivity no solutions, incorrect billings taking months to refund and absolutely shocking customer service. They are the ANC of telecommunications - ***** and *******ion come first and service delivery comes last...
