KreditBee — Fraud company spamming me with random phone numbers

We really need to file a collective lawsuit against this fraudulent company.
Imagine blocking every spam calls from this company, and they still create new random phone numbers to spam us. They know we have blocked them, they know we dont want anything to do with them. This is highly devious and illegal.
Btw how did they get my number in the first place. I have never hear of this company before the spam calls started.
