I checked the pay now box (in error) and ended reserving it as a non-refundable. I called one number and tried to cancel it and the guy only gave me grief. But then I used this number and the ppl there had no issues cancelling it and refunded the amt on 2 reservations. The number is 800.230.4898. I get the feeling the CSRs on this line is outside the US. The unhelpful lad is definitely an US based CSR.
