Locanto — Using my number for fraudulent activities.

I have been receiving calls my random men telling me if I have an ad on locanto. On the other hand, I have never heard of this website, never in my life visited their website. Someone is clearly using my number on their ads. Is this how people’s privacy is respected? What level of data breach is it? What is a company doing if not authenticating the number being used when anyone uploads an ad. I am sick and tired of such malarkey. Please help
Me get my number removed from this fraudulent ad posted on this website and prohibit the user who posted my ad from any such future activities.
