this caller demanded a call from me - An annoying caller --Please block

I keep getting data calls form this number to my cell phone. I called the number back and they won't tell me the name of the company or what they sell or manufacture. Is this the way they circumvent the do-not-call registry by NOT giving their name? i asked to be put on their do-not-calll list and they said they cannot do it, I must officially request that from the person who calls me - but it's a data call! There is no one there when I answer it.

I got a similar call and message about the failed attempt to deliver documentation. Since I moved twice in the past year I figured it may be legit. I actually called back and did get through. Turns out they are representing an old landlord of mine that I stiffed on 3 months rent. I don't know how the heck they got my new number but regardless I was actually shocked that the person I spoke to was really easy to deal with and respectful. You don't see that to much these days. Since they were willing to work with me I guess I am going to pay the bastard.

Called me at work numerous times back to back to back. I told them to contact me on my cell not at work. This was from a credit card I closed 5 years ago. I've never received letters from this company or any other before this so all late fees etc they are claiming have been accrued these past 5 years is ridiculous. Besides I'm doing credit repair now so I will go through that not some collection agency that may or may not clear it off my credit report.
