Not good service

I attempted to use my Makro RCS this morning at Engen fill station, where I usually do. However it was a bit different this morning. After the attendant put the petrol in we proceeded to swipe the card for the payment. The card declined and did so with all their other machines. I subsequently left my ID and credit with the fill station because i didnt have money. I called RCS and they told me my credit purchases for March was only added recently and they forgot to inform me. Because of this my statement showed I have credit but on their system it showed I'm in the minus. I feel this is totally unprofessional and unacceptable. I had to borrow money from my colleagues to pay the garage. Not happy about this at all.
