Did not hold up their end of the bargain

I have submitted receipts for almost 2 years and was very close to reaching the $30 reward. Its set up to encourage you to wait to redeem because the rewards accumulate faster as you get to higher rewards. Recently they sent out a notice that they were changing the rewards system. So today, I opened my app and instead of being very close to the $30 Amazon reward, I now have just barely reached the $5 reward. Seriously??? I get that this is not a big money situation and I get that yes, they technically warned me but seriously that was really shady. Zero stars.
