Somebody is having fun telling strangers on dating sites to call me, please help?

Long time ago i was active on dating sites, dating, dates not ending well etc.
I have had this problem for a year when i get random calls/whatsapp texts that they want to get to know me and they heard that i am looking. These come with varianle frequency, sometimes a few a week, then for months nothing, then something every day.

Now, today somebody texted me knowing my name, age and hometown. Finally i got some info on how he got my number, and it turns out he got it from a dating site. The site’s name he didnt admit, however, he was helpful enough to copy paste a conversation with a woman.

This woman says she is not there to get to know anybody, but she has this friend (me) who “likes older men and is looking to meet somebody”. The guy asked if he would bother me, this woman said “no, she loves it when she is being called, feel free to call her, no need to mention me”

All I have is a nickname for this “woman”, i have no idea which site it could be, i registered on a few and didnt come up with anything.
I am quite attached to my phone number, but my biggest concern is somebody having fun fcking with me and my data on purpose.

My best guess is that it is a guy I rejected, or maybe a bitter woman who was jealous of me.

Fortunately, this person never sends photos and doesnt seem to know more exact information about me.

Any input, ideas who would find this fun? I am incredibly frustrated by being fcked with.
