I purchased a Southwest ticket in May 2020 for a trip in September 2021. I canceled the trip, but I haven't been able to use the credit and I missed the window to convert the credit to points. I contacted Southwest via email and there was nothing they would do, but via chat I was told to wait until the credit expired and then they could extend the deadline? Any suggestions on what to do next? I'm a little nervous about waiting for the credit to expire.
