I do not know for sure who keeps calling me, but they use different numbers. I get the same message I get when they call from 620-665-7178. My guess, based on the other complaints I have read, is that it is from National Credit Adjusters. I am going to file a complaint with the donotcall registry.

This is National Credit Adjusters, a stupid collection agency with no clue.
Other numbers include 620-665-8721, 620-664-5496 and 866-570-6085. Unfortunately you cant stop a collector from calling you by complaining to the no-call registry; they are exempt. You must send a letter (certified is preferred) or fax telling them to cease and desist all contact. Luckily budhibbs.com has a free sample of such letter and I have the address and fax of these jerks: Write or fax them at NCA, 327 W 4th St, Hutchison KS 67501 or fax to 620-664-5947. These clueless morons have no idea who they are calling half the time and are under investigation by the Kansas Atty General. Talk to the KS AG also if they dont stop calling.

These asswholes called me a couple of times talking about some account that I never even heard of. Then the jack [***] asked me for my last 4 ssn. Now I'm concerned about someone trying to steal my identity. At least now I know who these people are and can file a complaint.

Message stated: This is an important call for Paul MERCKEL.
Please refer to account number 135.....

These people are idiots.  They use my name and leave a message about calling them back and refering to account 190...  This has been going on for about a month.  I also have been getting a lot of calls that show up as 111-111-1111 unknown caller or just unknown with no number.  These I get at least 3 times a day, in the daytime, the evening and even Saturday.
