Unfair Cooperation from Telkom

Four years ago I opened up a cellphone contract with Telkom using my number which was ported from MTN to Telkom. This is the only number I used for all the cellphone contracts that I had with Telkom. In the first two years I took out a contract which was upgraded when the term was almost up. On the 31st of November 2018 it came to my attention that I was a victim of a ********** activity at Telkom. I brought this to their attention after going through their self service portal on the app, I saw that two additional cellphone contracts were active which I did not authorise and did not receive any notification that such a transaction was being processed. I called their call center to find out exactly how they approved such since I know for a fact that I currently can't afford to even have a second contract due to financial constraints, I didn't get a positive response instead I was asked to provide an affidavit stating that I knew nothing of the two contracts that were **********ly opened which I did and submitted via email on 12/12/2018 and followed it up with the Mall of Africa store and explained the story about the ***** accounts and was asked to submit the same documents which I did on 18/12/2018. I was then told that they would escalate the matter. The bill by then was at R4000 and I asked how can I pay for the cellphone contract that I know of since I was threatened that my services will be cut off if I don't make payments. I asked if they can't separate the actual contract from the ********** ones so I can make payments and was told they can't and I have to accept that my services will be cut off. Mind you I was making the effort here to pay for the correct contract but the representative at the Telkom store in Mall of Africa just brushed me off to accept that until the investigation is concluded I can't use my number to do anything. Now it's January 2019 the bill is sitting at R12000 and just received an sms threatening me to pay R4600 or else they sending me to their lawyers and credit bureau. The audacity of Telkom to tell me this after I brought this to their attention instead of fixing the problem they are threatening me, what Bull is that? I joined Telkom because of affordability not this trash they are trying to subject me to.
