calls house phone and does not leave a message

Calls from numbers also registered, Washington D.C, they are a collection agency.   I have asked them no less than 10 times to put there request in writing instead of calling,  they tell me this will not ever happen.  So, I told them if they could not put it in writing, then the phone calls needed to stop.  They are very abusive when they do speak to you.  Most of the time they simply hang up when you answer the phone.  They have been calling us for about 6 months up to 25 times daily.

calls several times a day for some unknown person, never leaves a message

I get a call from them everyday, like 20 times a day.
the information they gave me was over a credit card from back in a state i never been to. they keep saying they have been sending me information in the mail. i still have yet to get anything. they also stated to that the CC place hasent gotten a payment from since 2001, and i ask them what the debt on the card was they said the balance was 1200, but then i asked them what the percent rate of the card, he stated 6%... in 8 years with no payment it only gained $200, that is crazy. i also think this is a scam, where i'm in the military, i'm going to report them...

These people are unreal!  They call from 201-537-4646 and 760-561-5214. Call 4-5 times a day. I made the mistake of answering the phone and the dude was so rude I was stunned!  I hope someone gets them to stop calling because this is crazy!
