Telkom ********** contract

Telkom **********ly opened a mobile account in my name that I have no knowledge of.I have asked them to cancel contract as I know nothing about it.This has fallen on deaf ears as they continue to run debit orders against my name.Please produce proof that I took up a contract with you????This is ***** and I am engaging my lawyers to have this ********** contract cancelled and obviously sue them the hell out of them
