Getting very frustrated with OpinionMilesClub......I've actually accrued a lot of miles over the past year (with tons of long boring surveys) but since yesterday I keep having a sign in problem asking for my MP# and then stating it does not match my Membership information or E-mail. Nothing has changed on my end. Their 800# just bounces me to a voicemail. I did send an e-mail but they responded with a generic - we will try to answer you in 72 hours. ?? Is anyone else having this problem?
