cryptsy.com lost money sent into account.

[rtr4]

Hello,

My last 3 payments sent from Eligius did not arrived on my account in cryptsy. I contacted the customer support and they promised to respond within 24-72 hours but now it is a 7th day and no response.
The money were not added to account. Same happened to my friend.
Has anyone similar experience with cryptsy?
Any advice what to do when they keep silent?
Thanks
