RCS is a complete waste of time!

RCS is a waste of time. I tried using my Contempo RCS card at a few other RCS stores only to have it decline everywhere. It only works at Contempo, Checkers and Pick n Pay. Yesterday I drove to 3 Pep Stores and my card declined at all 3!! The cashier then phones RCS, holds on for 45 minutes and then hands me the phone where an irritated customer service person tells me theres nothing wrong with the card, try another store. I drove to Pep stores in Strand and the staff refused to help me cause I have an RCS card. They said maybe your limit for the day has been used. ?? Then another one said sorry we can't phone them we have a landline and it can't phone that number. Then the manager asked, did you get an authorisation for this. Drove to another pep stores where the cashier finally gets through to RCS but the customer service person started shouting at me on the phone!! Not only is this embarrassing but a complete waste of time!!! Whats the use I have this card but everytime I want to use it The store needs to call your *********** customer care who says theres nothing wrong with the card after making us hold on for 45 minutes!! RCS this is pathetic!
