Poor service

Extremely poor service, I have been trying to update my account details from the 14th May 2020. after numerous emails and calls to their contact center, this request ended up with Busisiwe Tunzi a so called service consultant, where the circus continued and finally she informed to submit a certified copy of my ID. this could have been communicated at the first point of contact. I have asked for the customer service managers details and she has yet to reply. now im wondering how long this is going to take to resolve
