Sorry for your (potential) loss, but honestly speaking, if I see a service with such a domain, I would just avoid it. It has become a trend nowadays where people get scammed by services with odd domain names.
No service that legitimately plans to conduct fair business will ever use such a shitty domain name. It doesn't represent trust, it doesn't represent professionalism, and it reeks of shady practices from its initial looks.
Well, Holytransaction working since 2014 and so far it wasn't one of these shady services. Maybe their name is a bit strange, but I don't think it really matters. I'm using this service for few years already and I don't have any complaints about it. Offcourse, I don't use it hold big amount of coins, because it's online wallet where we don't have control of private keys.
OP, I hope they will respond to you soon. Nowadays we need lot of patience when it comes getting response from support on exchanges. It looks that mostly exchanges, wallets and similar services just don't have enough staff to solve various issues.
