Got a note from someone that said they've been trying to call me.  

Yeah, right.

The card said to call this number 704 989 0946.  The card had no address or other identifying information on it, except for Kate Jones at the bottom.

So I called --- they're trying to sell you something.

Just moved, received a card in the mail saying:
"Welcome Neighbors

We have been unable to contact you by phone.
Please contact us within (7) days.
We have a parcel for you.

Please Call 10:00am - 9:00pm Monday - Friday
And 9:00am - 12:00pm on Saturdays

(704) 989-0946
Ask for Kate Jones

Your parcel # is ____"

I called and asked about the parcel, and the guy said they wanted to welcome me to the neighborhood with a $100 gift card and a free water treatment test. I asked what they were selling and he was not straight-forward so I ended the call.

There is no parcel, just a sneaky attempt to gain your business from a water testing company (?). Which company? Who knows, they are that sneaky.

Same as statement made by Nick on 09/01/2013.  This is definately a telemarketer.  They want to know if you are married, your spouse's name and what time you usually arrive home from work.  They don't even know your address and want directions on how to get to your home.  Be cautious.

but how they do your name?

Got the same mailer.  Seems fishy...
