Ebookers, Expedia ****s, non-existent customer service

We booked flights on Expedia (Ebookers) on 28 Aug, and the policy states that changes can be made within 24 hours, which is 11:30 pm the next day. It is impossible to get through to the call centre, after numerous attempts by email and telephone we finally got through to the call centre and the agent gave us a ridiculous price to change the ticket for a shorter duration on the stopover. When i mentioned the 24 hours change policy he says it is 5 minutes too late, and we have to pay. After several more emails Priya Raina called form Ebookers India office and promised to get back to me as she is the escalations manager. I called back the next day and was told that I cannot get assistance as only Priya would be able to help me. This has costed me a lot in international calls as there are no local numbers. To date we have no response from anyone. Please do not use Ebookers or any subsidiary company of Expedia to book your travel, it seems like a ****.
