After trying for months to get a refund from my travel agent regarding Covid pandemic cancelled flights, I was advised to try section 75 as I had paid by Nationwide credit card.What a waste of my time and effort.I filled out on line forms and providing photo evidence of flight e tickets and travel agent apology letter.After 8 weeks I received a letter from Nationwide who required me to provide evidence of the cancelled flight! The fact that in June there were no flights anywhere this seemed to be a ridiculous request.Take my advice,don’t count on Nationwide to get you your money back.
