I have sent numerous emails and made phonecalls to Santander. Constantly passed from pillar to post and then cut off! its sooooo frustrating. However I was very happy to discover that 8 out of my 12 flights were actually booked on my tescos visa card, and I have now rang them who told me to put it in writing. I have printed off the front page from the KTHY website and attached this to my tickets to try and get refund. I am just waiting for them to come back to me regarding the Atlas jet website, which states replacement flights are available!!!! I will print off the flight arrivals for Manchester airport, and the flight departures from Dalaman airport as proof that the flight this saturday is no more....what more can we do!! I am going to see how I get on with the visa credit card flights first, then fight for the debit card ones (which were just for three of us on July 24th to Dalaman.) Thanks for advice....any further advice appreciated..
