I have tried for many hours to contact Expedia by phone at 13 pence per minute and no one answers. I have written 7 e-mails and they reply telling me to phone. I have sent them my number and no one calls.
I now face a loss of business because I cannot change a flight. I normally never use Expedia for my monthly intercontinental flight. I never will again. It is the absolute worse service I have ever encountered.
A call to Expedia USA did result in a reply but they cannot enter the same system and cannot contact them on other numbers.
ADVICE DO NOT USE EXPEDIA.
