Lusha?

I've had an increase in spammy sales calls on my personal number recently. One salesperson was kind enough to tell me that they got my personal number from a company called "Lusha".

I've never heard of this company before and so have never given them any personal data or permission to share it.

What would be my options here to, at minimum, have them stop sharing my personal contact info with random salespeople, and delete the info?
