8 years after getting rid of Telkom i am still being hounded like a ********.....

Hi,

I keep being called by debt review agencies saying i have been handed over to them by telkom mobile on an outstanding amount. My credit score is being affected by this but i have not had any contact with Telkom since 2013 and this had never come up until the end of last year. Not once has Telkom contacted me or sent me a statement or account details. I cannot even dispute it as i have no clue what my old account details were. Its not fair that 8 years after a contract ends i am being haunted by a R200 amount that i would love to just pay to get Telkom out of my life but i cant as i dont have my account details from almost 10 years ago.
