Impossible to reach COPA via telephone.. I tried the 305 number and the 800 number listed on their website for USA residents. You either get a quick busy, circuits busy or unable to connect. I even sent them a tweet via DM 4 days ago and no reply, this is ridiculous. I have a substantial change in schedule and the email they sent me only lets me credit for the future or change travel within the next year. I want a refund.. I’ve never wanted to file a DOT complaint before, however I’m losing my patience. This is going on for six days. Unbelievable. Has anyone else experienced this?
