Fake RoyalMail scam

https://royalmail.ref419.com

I was sent this SMS

"RoyalMail:Your item has a £2 unpaid shipping fee, to pay this now please visit https://royalmail.ref419.com Your item will return to sender if unpaid"

I know its a scam because the number that the SMS was sent from didn't exist
I have already reported it to Google safe search and Namecheap hosting

another dead giveaway (the website was using a subdomain which was ref419.com)

I don't know what else to do so I'm posting here.
