I've no idea on the question you asked, but sales response time != support response time. Sales works business hours, so to speak. So if you just emailed them a lil while ago, give them till monday or so (I'd reccomend anyway).
Why bother? Order a VPS from HostForWeb and you'll be up and running in a couple of hours (maybe a bit longer since it's Sunday).
I don't know how their plans/prices compare with the other company but if you want service & support it's always worked for me.
DedicatedNow do not hide the fact that sales is staff only during business hours. Support is there when and if you need it whatever time of day. They are not officially accepting orders at the moment, as indicated on the site.
