Its a complete clone website and they are running this for specific users as they always do. You did the right job by reporting this website and hopefully google will take proper actions from their end. I just tried to visit the website and its taking too much time to load although my internet connection okay.

In anyways, its good you have shared this cause sometime some users or maybe majority are accessing it through their respective laptop and pc and of course chances to mistook an original site to these lousy clones or fake site is inevitable especially fir careless people.
In some cases you will get the fake/clone one on top during search. I have already seen multiple times that fake website url is showing on top and real one is showing below that. Actually the do strong SEO to keep their fake website on top for visitors and usually people click on the wrong one without checking the url properly.
Always rule to bookmarket all sites to avoid hitting a scammer's site. Thanks for sharing.
Yeah anyone can keep his/her browsing safer by regularly using the bookmark option and it really works IMO.
