RCS invalid card despite many visits to the rcs store

I lost my rcs tiger wheel and tiger card went into Makro saw the rcs consultant who called rcs and got me a replacement card she mentioned I would be able to use it after a few days a month went by tried to use it at several stores card got declined. Visited the rcs store Makro today waited for over an hour, after an hour the consultant mentioned will be able to use card immediately , went shopping with a trolly full of groceries and card was not accepted said invalid card. I am fed up now and need access to my funds!
