Had to shut down shopify store due to hack

[Sw1946]

Hello I would like some help please!

I’ve recently had to shut down my Shopify website as I have noticed when customers google my page they are taken to a different catalogue page rather than my products. It’s very frustrating!
The phone number on the website that’s taken over my page links to this facebook account,FYI the phone number on the website that’s taken over yours links to this facebook account, which seems to be a scam / fake too.
https://www.facebook.com/profile.php?id=100076385355798 which seems to be a scam / fake too.
I have reported this to Facebook, but 

I have no idea how to get rid of this, please help!
