I have been trying to get a refund from an online travel agent for over a year for flights cancelled during lockdown. They have finally agreed (with a fee). Now they are asking me to confirm the card details. I have been speaking to the same staff member via email. Is it normal to ask for card details for a refund (would they not have these on file already?)? Also, I am thinking giving this information over email is not sensible so I was thinking of phoning them. The number she has phoned me on is not one of the listed numbers on their website either (probably an outsourced call centre) so I am thinking phoning the main one would be safer. I don't know, Not sure what to do, this company is terrible (and I'll never make the same mistake booking flights again) but I just really want my money back now.
