MTN sucks

I would give them zero if that was an option. MTN has allegedly upgraded my contract without my consent and debited an exorbitant amount locked into a 24 month contract through some third party called Empowered. I have not been provided with proof of an agreement to this upgrade and have been sent from one department to another without any resolution. The final straw was when I had to call this Empowered company and ask them - a company I do not have a relationship with nor consented for my personal information to be shared with them for details - naturally that call got cut off without any help. Is this not a POPI ACT breach, also no proof of debi check mandate accepted for this amount? I now cannot cancel this contract with MTN before November 2024 and am worried that my credit record will be impacted adversely because I reversed the debit order at the bank. I am raging mad and need help.
