Does not give 5 automatic coins after reaching 100 each week

Decent app except there have been multiple occasions where I have reached 100 coins in a week. They claim after this point, you are supposed to receive 5 coins for every receipt after that for the week. This has definitely not been the case for me. I tried contacting them about it and got generic copy and paste responses that did help at all. Better customer service is needed.
