********** account debt collection

I have never opened a Telkom account and they keep phoning me regarding an outstanding balance, I explain to them every time that I have never had a Telkom account and I would please like more info regarding the account, they REFUSE to send me a statement or give me more info regarding the account. If this is against my name and ID number, do I not have the right, according to the PAIA act to obtain this info against my name so I can provide them with a complete statement from the police?

They are literally giving me ZERO info and harass me at work and my personal phone.

Anyone that can assist me with this?
