Called earlier this morning - was told there was nothing they could do.
Waited a couple of hours, and just tried again.
Entered card #, "membership rewards", and then "agent". After about 2 minutes on hold, while the very friendly rep checked into it - she came back and told me they could do it, however I would have to call back on or after June 15th to make it all happen. She told me it was noted on my account, and would only require a call back on my part after Jun 15th. Will definitely be calling them next month!
