I tried to claim a delay repay for a trip from crawley to london bridge however it was rejected on the basis that the train didnt exist. I think that my mistake is that i put it through on the southern trains website instead of the thameslink one. I now do not have a the ticket so i cant resubmit the claim on the thameslink website. Can you advise on the best way to proceed. I thought that southern and thameslink were the same company
