Feel sorry for the families involved in this. I had it last year with Goldtrail. The situation with the CreditCard refund is as follows
1) If you have booked directly with the company in administration then you can claim from your credit card provider
2) If you have paid the money to a travel agent (high street or online) who has used Onur/Agean/H4U,the deal is with the agent so, a claim needs to be made with the CAA as the travel agent is not the one in administration
Took me 9 months until I was refunded and was a pretty simple process. We're over next week and fortunately for us we used Thomas Cook this time,,,good luck to the many involved.
