Need Info On Bridalmarketplace.

I ordered a dress from bridalmarketplace in may and I can`t get a hold of the people anymore. They switched companies but are still taking care of previous orders. My wedding is oct 4 and there current site says my dress isn`t expected to be here until sept 20. I called there 1-800 number and all they have is a machine talking and I`m not able to leave a message. This makes me very leary. I have emailed them but they won`t email me back. I will still need alterations and I am getting very frantic. If anyone has a phone number I would appreciate any info.
Thank You
