BIGGEST CON ARTIST JUST TO GET CUSTOMERS!!

I belong to the Mica rewards programme. Received a message on my phone stating that I had a certain amount on my account to be used. Today I went in to get something from Mica in Middelburg and when I mentioned that I had a credit balance on my card was told that on their system it showed a zero balance. For a long time Mica has been making a big hoo ha about joining their rewards programme and that it gives you big cash back bonuses with every purchase being added. This to me seems like it was only to encourage people to spend more money in their stores with the promise of rewards, (WHICH DO NOT EXIST!!) I feel that they are conning their customers. Why even bother sending sms messages stating you have 'x" amount to spend when it does not even exist?? I think I will rather in future support their opposition i.e. Builders, that do not try and ******* their customers just to make a buck!! SHAME ON YOU!!
