The phone number is for Domains by Proxy, which is the Identity protection company and not the person who reigstered the domain.
If anyone has been affected by this please email COINGATHER.COM@domainsbyproxy.com a complaint, saying the site took your money, and that you will bring legal action if necessary. Include your Coingather username and the approx value (in USD) that you lost. They need to start hearing from us all.
I am personally launching a dig campaign, so if anyone has information about the lads at CoinGather let me knw. Names, emails, phone numbers, ip addresses, twitter handles etc.
