********** and reckless with personal information POPI act

We have been customers of MTN for 22 years. Recently they allowed ***** on the account, and it seems like their investigators are just as *******. They are not getting back to us, and try to debit the account with R6000 this month. We send avadavits through and everything no one is coming back to us. We know reported MTN with the POPI act. They are reckless with the personal information they have on record. ********** working there and absolutely *********** staff. Not helping you at all. I ask a senior manager to call me, nothing
