VERY DISAPPOINTED! Mugg & Bean CLearwater

It was my birthday on Sunday 4 May and we were in Clearwater Mall normally I go to KeyWest Mugg & Bean it's become a tradition on my birthday I go for my complimentary "birthday" cake and then we eat there. But when I got to Clearwater Mugg & Bean I told them I have the app and that I was there for my birthday cake. They told me I needed an sms to get it and I said but I didn't get an sms and I have never had issues at Key west even at times when the app didn't want to work they would still give me the cake. But I was told by Lorraine and Phakisa who even had an attitude that there is nothing they can do I must phone the app directly on a Sunday????? Needless to say Mugg & Bean Clearwater you lost a customer for a piece of cake our bill would have completely made us for the cake but your managers are clearly trained that customers has no value.
