No identification on the voicemail, said he had mail he wanted to get out to me. Pretty clearly a scammer.

They are trying to sell a service. We have asked them to quit calling. Please make it stop. Thank you.

Caller called on a Sunday.

I told him we are on the national do not call registry and he is not to call us again.

Its a scam. Claiming to be from Microsoft. Microsoft does not call unsolicited. Check their website for more info abot this scam.

2nd call was the same person who called the 1st time.

This number continues to call at all times of the day.

they have called multiple times!

Yet another call from yet another number from "Card Services." That's 2 in 2 hours this morning. END THIS.

It was a recorded message but I stayed on the line and got the name of the company.

Once the recorded message completes and a person is summoned to speak with, they hang up after being informed of the no call status and repeated requests to discontinue calling. I have no credit cards.

If you try calling them back, all you get is a recording.
