Where are the stars?

I have been using this app 2 to 3 times a week. I went in today and my three stars for the free frappe which is one of my favorites were gone. I bought 2 frappes this morning. I just looked and 2 stars are there but I should have 5. Dont know what happened to the 3 that I had on there. Ive used some of the other deals and they work. Please fix, I want my stars.
