Vodacom does not adhere to RICA requirements

Oh my hat! We moved house in August and I have been trying since then to change my physical address on my Vodacom statements. They now have 3 different addresses on my statements, and all 3 are incorrect! After numerous phone calls, each of which was problematic because the agent cannot hear me, or misspells stuff, I decided to write an email. I included my latest municipal account so that they have proof of my new address. So then they can just copy and paste the new address, right? Wrong! I keep on getting emails from their customer care asking for personal info. The latest one wants my ID number and info about my banking account! Have they gone mad? Really, how is it possible that Vodacom cannot do a simple little thing like changing an address?? We are nearly in 2023! I am giving up now. If these people do not want my correct address, fine. I have proof that I tried to change it. So much for adhering to RICA requirements, Vodacom!
