Yellow Pages (Trudon) and Telkom Dilemma

I have had a contract with Telkom for over 4 to 5 years now. Recently i was called and offered an upgrade on my line and i accepted as i was going to get better Internet speed and quality for a less price of R899 from R1300+. Three months after the upgrade i started getting invoices for R1500+ and i queried what this was for starting from the 2nd of August 2021. I have gone to Telkom offices in Richards Bay KZN 2 times which is 2hours away from my home, i have called half a dozen consultants about this matter and they have all promised to escalate this matter. The only information i was given from all these efforts was that, I had joined Yellow Pages also known as Trudon, which i have stated many times that i have no knowledge of. I also queried why if they did not know this company, why it showing on their invoices they send me. I was told to call them myself and cancel with them as i joined them, the numbers i was given were not answered, the Email i sent was not responded to.I have not received and update from Telkom on anything they have done to sort out my issue after all the attempts i have made to get this resolved, instead i recently received a message from Telkom stating that if i do not pay R1653.27 immediately for my service not to be cut off. My statement with them has risen to R3386.23 in the last 3 months. I have been paying R900 every month which i know to be the agreement i have with them and yet i owe them. Can someone please help me because my business depends mostly on having Internet access as it is an Internet Cafe, i have tried all i can but i am tired now.
