Caller: Shop.com.world or shop coin world

The person speaks so fast but when asked what website they are talking about listing your business on for free . The person says one of or team members will call you. Comes up as spam . As speaking i was trying to put the site in and asked several times what is the correct site you are mentioning ? And you get a thank you mam is shop com world. I asked as is shop dot com dot world? Then the person says shop coin world so anyway appears to be looking for leads for retail business to list in a newly formed registry made April 2020.
