Continuous attempts to open *****ulent accounts in my name by MTN since 2006

I've never been a MTN account holder. +/- 2006 - I had a "sudden" debit order from MTN. Went to MTN to asked for more information. They refused to provide information. Went to FNB to report the unauthorised debit order. FNB confirmed issues between MTN and FNB and they immediately cancelled in the transaction. +/- 2013 - Same situation with "sudden" debit order, FNB reversed the transaction. If I recalled correctly, I had to submit a case number. Now in 2026 MTN do not take money. But somehow have my cell number and is demanding R21k for an account I do not have Their lawyers "Shapiro etc" called. The do not have my cell number (their "computers called me", cannot produce any paperwork, they do not have my e-mail address. MTN what is going .... again?
