I had an itin with 1 segment cleared, 1 segment waitlisted.

I changed my reservation with an agent on the phone (.bomb errored out every time). She claimed to have redeposited the RPU.

New itin has 1 segment cleared, 1 segment waitlisted.

But, I'm down a new RPU now (and never got back the one which will be expiring in early 2016).

How should I handle this? Wait until I travel and then ask the MP Service Center to deal with it? I'm afraid if I call in now, they'll screw up the existing itin (either losing the cleared segment, a redeye, or losing my place on the waitlist for the other segment).
