I tried calling the number on the back of the Humana card and after searching through phone tree for about 15 minutes found that I had earned $5 on the 9th of January. I don't know why I got the $48, which seems like an odd number. Can't find any other way to contact anybody for a question. The whole new interface is terrible! Lots of pretty pictures with older models exercising but beyond that pretty pointless.
I apologize for the concern with your rewards. I can see that your account is showing the correct amount of rewards. Let me know if you are still seeing an incorrect number in rewards.
