RCS preventing Edgars from doing proper business

Pretty frustrated about the way Edgars accounts and cards are being handled by RCS. Its been months with no potisive outcome.

I've visited our local Edgars branch (Centurion Mall) since July 2020 to have my Edgars card (original from 10 years back) replaced with the new card but the system is apparently offline since then. According to the staff at the branch there is no way they can replace my card or open a new account for me since the relevant systems are offline (I visited the store several times since July, and my last attempt was today).

This is absolutely ridiculous! How can Edgars do business without these/your systems working? How do you work if you can't offer the services/systems you are paid for?

I need to buy items from Edgars but can't use the credit facility because of the age of my card. And you can't help me with a replacement or even a new account. What am I supposed to do? And more importantly, what are you going to so to resolve this?
