Poor service & impossible to get hold of travelstart via email, telephone & chat.

Hi

I would just like to make a note of Travelstart & their poor service. I booked tickets through them about 2 weeks ago. I've tried to amend a title on one of the tickets. When calling I was put on hold for 10 minutes after going though some voice prompts. When I eventually spoke to a human being and told her about my amendment I was again put on hold and ended the call after another 10 minutes. I have emailed them to both ********** as well as ********** - no response. Then I tried their chat service & was told that it was not available. Is there any way to get hold of this place?
