I bought a hosting package last sunday with domain name included(caner.us). My account was created in the same day.

But when I check whois records, my domain seems to be still available. How long it takes to register a .us domain name?

I know that dns redirection takes couple of days, but this is not the issue. Maybe they forgot to register it?(I paid with paypal)

i recommend you strongly to use a private medium for that issue
