DISCOVERY BAD SERVICE

I sent a complaint through because of my credit card not being correct. I was told to email clientdocuments@discovery with proof of payments which i did on 1 March 2023 and to date habe heard nothing. Why do we even bother doing what we are told when no one helps. As iv said im not in the country any more and would like matters sorted before i get slambed with legal action which is what SA like to do.
