Wrong favicon showing from other site

This site (gogopowerrangers-9ay.pages.dev) is pretending to be an AMP version of our content (amazingtoursbd.com) by using our domain in its canonical tag. It misrepresents our site and hijacks our favicon in Google search results. It somehow injected some code in my server and verify the search console. I removed all the code but in search console can not remove amp site. What to do now?
