The Mirraw wallet does not allow the customers to use the full balance. That is certainly not fair. As a customer if I am buying items from your website and in turn getting the rewards, you should not restrict me from using it fully. Also regarding your last question here "Should we follow up to make sure you're satisfied with your order" does not allow me to choose "No" as an answer. This is certainly very unfair on your part to force me to choose "yes"
