Pathetic Telkom Service

I have a cell phone contract with Telkom of which is coming to an end. I requested for an upgrade to be done however on the 03 Feb 2022 I was told it was declined ….then on the 03 March 2022 I received a sms that the application for the upgrade was approved followed by a call from a consultant that completed the application. I was given a package for R349 for 2 Huawei P smart 2021 devices and was told it will be delivered to me after 7 working days.....after me contacting Telkom on the 7th working day of not receiving the device I was told the is no application, however I received an online OTP pin to verify the application.so due to the incompetency of Telkom I requested a cancellation on my whole contract on the 5 March and requested for my number be changed to a prepaid....Telkom failed to change my number to a prepaid and on the 16th March 62 Gigs of data that i did have was taken away by Telkom …but I am supposed to pay a full months subscription....this is totally unfair and I am dissatisfied with the service that I have received from Telkom ….I have lost a lot of money and time with calling in to the call centre and receiving incorrect information … I am not sitting with no service on my sim card that is used for business and I have lost 62 gigs of data and Telkom is not willing to assist me with positive feedback …..this is unacceptable and I am not prepared to pay my last subscription until my query is resolved.
