I have found a domain that is pishing my own domain. Help

Hello. I found this domain: ​http://peluka.info-2b.ct.vtex.com.br that is supplanting my website: https://www.peluka.info and I'm trying to contact vtex to take it down. But I couldn't open a ticket to do it. Someone can help me?

I​ found it after I did a shop on a supermarket. It were supplanting my own email.

Please any help?​
