Discouraging client experience with unauthorized additional chargers!

I recently received my invoice for the month of July only to find a once of subscription fee charged extra. I then logged into my Telkom to view any information thereof since i did not subscribe to anything unusual or use any new apps that would bill my Telkom account, no info could be found however i noticed that for the current month a fee is billing. i then immediately emailed Telkom on the 06/08/2020 at 09:08 and to date have received no response. On 08/08/2020 around 08:40 i then proceeded to create a chat through the app to get assistance. i then proceeded to explain that i have no knowledge of any subscriptions and have not done anything new with my telkom account ,furthermore requested info about this subscription. i was assisted by Mbali Simelane , who continuously mentioned that I WAS THE ONE WHO SUBSCRIBED despite me mentioning time and time again that i have no knowledge of this charge this my enquiry. the subscription furthermore is for value added services through a company who is partnered with Telkom, Akinga vertical service. i requested that this be cancelled immediately however all mbali could do was escalate the matter with no actual reference or follow up measures in place. i have not requested or signed up for anything additional so please can this be cancelled immediately and the amounts rectified, furthermore please do not sign me up for anything without my consent. It is honestly frustrating as a client to always be a fault with Telkom and that one needs to resort to such platforms to get assistance. perhaps you should consider having a look into your client service and handling on the front line staff as this is not the first time i experience such! I think this is my deal breaker now where I consider changing service providers once my contract is over since there is no change in your customer service.
