it do take several months for them to process the refund, like 3-4 months generally speaking, I mean they are not a huge amount of money, majority of them are like 10-80 dollars, so I would rec just checking with them next time when you need to call them to cancel another ticket. 7 months are a bit long, I believe they may just forget it. My average is like 3-4 months.

Yes, some representatives will just directly say as this is the involuntary cancellation, we will waive the 25 booking fee, some you need to tell them it should be refunded, but majority of them just refused refunding the booking fee, only agree to refund the tax.
