Who called from 6032856422

Called and said they were with 'Delta Management' and immediately asked for my date of birth to confirm their records.  Delta Management a scam????

They called my Grandmother in California looking for me, or my Mother. Was trying to get information from my grandmother. She did not give them any.

Called father looking for ( not ) me since they had the wrong name.  Delta Management Associates harassment continues.  Delta Management Associates reported to FTC along with Kevin Mclain with Delta Management Associates now calling from 603-285-6426

Voicemail with audible callers in the background. She said she was looking for me and needed a call by tonight not saying where she was calling from.

Receiving calls from Delta Management Groups.  These calls are unsolicited.  Their telephone number is 1 603 285 6487.

Would appreciate information on how to stop these calls.   Their first question is to verify my date of birth which I did not and will not give to them.
