ok funny one this, ive been offered a refund on a tunnel crossing by a 3rd party and theyve asked for my receipt... i dont haev it.

ticket was paid in cash at the booth so cant get details from credit card statements.

im thinking best way to approach this is to try and prove i used the tunnel and then get the prices of the ticket, which is a best endevours.

so, suggestions? im guessing if i ring eurotunnel they wont really care?
