Bankbazaar — Fraud scam intruding privacy and unwanted calls and constant severe disturbances

I don’t why these guys are calling me again and again, Atleast 100 calls last 3-4 days, I’m distressed and agitated . Inspite of requesting them and sending mail to block still continuing the nuisance, invading privacy and torture to the maximum . Please stop these guys, they are a threat and no ethics or morals.
