complaint about Expedia ticket refund

Hi,

I wish to lodge a complaint against Expedia for having promised and not

refunded my cancelled tickets from 6 months ago.Every time I call, they have been

giving me excuses about tickets being misplaced and then having found it and

that it was being "processed", it has been 6 months since I cancelled the

tickets and have received only 1 ticket as a refund and 2 other tickets pending

as of yet. Their reply always is that it is being processed and that the refund

will take 2-3 billing cycles to show up on my credit card.

I will be happy to provide more detals once I hear back from you regarding

your charges to this process and the process it would involve.

Thanks

Anu
