MTN shocking service

I have been a customer of MTN for 23 years and am appalled by the poor service I have received, and lack of communication - especially as they are a communications company.

I had defaulted on my account and made a payment arrangement. Before this arrangement was concluded they re-circulated my number. I am told this is their policy to recirculate numbers after no activity for three months. If it is hard barred off course there wont be any activity, but no mention or question asked if I would like to retain number once account is paid. Nothing in my contract to the same either. I have spent hours holding to try sort it out and have references galore of it being escalated. Still no coms back. As a result they have exposed my life as the new owner is receiving my OTPs and verification codes for all my social platforms, as well as having access to those platforms. I'm sure in terms of the POPI act this is a grave contravention.

Further to this they have allocated the funds in correctly, so are still mailing me that the account is in "arrears" but they can not respond to my query to get the number back or at least help to get the codes so I can move all my platforms over, as I have forgotten the passwords. Been so long that I had to login as everything was on my phone and linked to that number.
