Call forwarding fraud, avoid this number, it is a scam

I received a call on Truecaller showing Blue Dart. When I answered, the caller said that one of their men had brought a courier for me and asked me to receive it. He said he would send the number. When I saw the number, I got suspicious because it had an asterisk (*) in it. I told him this number is not from the company, but he said it was a toll-free number. When I dialed the number, call forwarding was activated. So please beware of such frauds.
