RCS Self Help App Not Working. No Assistance...

The Service from RCS Customer Services is honestly pathetic. Rude staff and dropping lines when they run out of options, since last week monday i have not been able to log into RCS Self Help App including Edgars Self Help App, "Authentication Failed. I have e mailed RCS 3 times, i called 5 times, no one seems to assist and get this App up and going. I have been sent from.pillar to post, i have been told to delete the App, and re install, go through the selfie authentication process over and over 6 or 7 times, changed the passwords, NOTHING WORKS, then i am told to contact the ***** division, i informed them as well as customer service that i have changed my contact number TO *** and the number i previously used 082 753.... to receive authentication messages, is no longer used, this was changed by customer services and i was informed by customer services that my details were changed successfully, i was also informed by the ***** devision that all my details are correct. They sent me links to click on to innitiate selfie verification whice i as told was successfull, and i should be able to log in, surprise.... all still the same. Authentication Failed... ***** department checked my accounts are NOT BLOCKED, and there is NO ***** on my accounts on none of them. My device and sims were stollen on Sunday last week. I immediatly remote locked my phone and blocked both sim cards, bothe my networks blaclisted my phone and blocked my sim cards, i had successfull sim swops on both my simcards as early as monday morning last week. I am now using an old phone previously used up untill i receive my new phone from insurance claim. I changed my number with RCS customer Services and i was advised it was successfully changed, selfie Authentication done perhaps 10 times and also by links the agents sent to me. This is now becoming rediculous no one to assist no one communicating or relplying e mails no one following up on complaints. Please can RCS sort this out.
