Pathetic customer service from Nedbank

If I could give less than 1 star, I would have.

I live overseas and have been trying since the 11th of January 2022 to change my cellphone number on my account so that I can reactivate my bank account.

I have send numerous emails, I had video calls with Nedbank, I have supp**** and comp**** with all their requests. Now I am not getting any feedback, no responses to my emails, and the only thing customer services are doing is to "escalate" the complaint... with out any success.
