Telkom allowing 3rd party company (Trudon) to add services to their Customers accounts

I'm a frustrated Telkom customer that are tired of calling them to sort out a service they had a third party (Trudon) add to my account that I have with Telkom for a service I never asked for. When I phone Telkom they say they do not know how this service was added to my account that I have with them and that I should phone Trudon to cancel the service and then phone them back with the cancelation reference number. They added the service in Aug 2018 and every month I try phoning without it being resolved as many times I do not get the opportunity to speak to an operator and when I do, they cannot help me. When trying to phone Trudon, I only get a “we are experiencing a high call volume and then they drop the call. This service has been added to my account without my consent as the account holder. This is *****ing from their customers and is totally unexpectable! As a paying customer I expect service.
