Website is not even functional anymore and I couldn't find informations about the website , I checked the domain details and It was literally created on 04-jan-2017 so I'm not sure how you find them but from the look of it , they probably wasn't planning to run for a long time and simply walk away with user funds.
http://servicehostnet.com/domain/bitnowa.combitnowa.com si scam , waited one week now and nothing arrive , please beware.
Actually now it seems they have gone for forever, you should have checked about their reputation before trusting them. Any service that claim to sell bitcoin for paypal can't be reliable as paypal strictly restrict this activity. Sorry for your loss..
Only thing I can find anything about them is some random stuff asking for a vouching of services from the beginning of the year on Jan 4th.
Their website is offline and only comes up with a cloudflare page so they are gone for good.

Because they would need a license to operate as an exchange there now and that costs alot of money which was put into law a couple of months ago.
Just watch the latest documentary to see how that transpired.
