Not sure I wouldn't escalate on the phone or ask them to show me where the h*ll this is. Lots of problems with website and I wouldn't know where to do this

Complaints is the only place https://accc-prod.microsoftcrmportal...da-contact-us/

and then go Topic: Flight Pass Product Sub-Topic: Complaint Issue: Other

But that would be a last resort--would pursue on the phone first and get them to deal with it expeditiously

Alternatively you could go to the refund form:

https://refundservices.business.cond...refunds/create

choose customer type: Passenger
Choose the option which best describes your refund request: my option is not listed
and then describe in the box at the bottom

Not exactly satisfying -- nothing in the flight pass section I could see either

On the plus side, these usually work like a charm with no issues, immediate recrediting etc. This has never happened to me fortunately. Near the beginning of flight passes a few people reported issues similar to yours (improper use (too many credits taken)/issues with recrediting of flight pass credits after cancellations) on FT that resolved themselves within a couple of hours/days (without requesting it).
