I have had calls from this number claiming to be from American Express

A person with an Indian accent called claiming to be from American Express. They were looking for someone with the same last name as mine but a different first name. He then gave me an address from another part of my state that I have never lived in. He then insisted I give him the last four digits of my social security number. I repeatedly refused. He said the only way I would not receive any more phone calls from them would be if I provided the last four digits of my social security number. He became quite rude so I demanded to speak to a supervisor. The next person also had an Indian accent and he said "Good afternoon" even though it was morning here on the east coast. We also went through the whole wrong name, wrong address and social security number.  He also asked for my date of birth which I refused to give. Eventually, he gave up and ended the call.
