bill collector call all hours of the day and night

Received a call this morning (5/5/10) from some person (heavy accent) asking for my husband. I asked who was calling and he said Troy Sanders or something like that but did not identify a company name.  Before he talked, I could hear a lot of activity in the background (like it was a call center). I told him my husband was unavailable at the time and he said have a nice day and that was it.

Some guy who he says is Ryan Sanders at this number keeps calling my house trying to fish for information.  Every time he calls he says is for some type of debt, but is something different from the previous call.

1st call: Debt collection of credit card - $1,097.15
2nd call: Debt collection for unpaid rent $460.00
3rd call: Unpaid military expense $780.00
4th plus calls I keep hanging up

I feel harassed, please do something about it.

Thank you,
John

Did not leave message. Another number in the long line of 240-374-xxxx phone calls. I hate these people.
