Subject : Cancellation of ticket.
I would like to draw your kind attention that I bought an air ticket to go on a tour to Thailand on 15 September 2014 form your travel agency. It was flight No BG 88, seat No E-5. But I for an emergency reason I will not be able to go there. So I have to cancel my ticket. Please cancel my ticket and ensure me about the cancellation as soon as possible.
