Mrs M Rewards Hoax?

Mrs M Rewards cards appear to be some kind of hoax - I have tried to find a way to see what points I have accumulated over at least a year of swiping with every purchase only to find there is no way to check - the app customer service referred to does not seem to exist in Google Play Store. Please note the answer from customer support referred to "our app store" - a bit strange - what does this mean? I contacted customer support in this regard again and have heard nothing further. Please can I get proper direction regarding this?
