Found this number on my Caller ID display when I got home from work.  No message left by caller.

Similar to the call I got. I asked the caller if he had a Do Not Call list as I was already on it. He then ignored my question and said something like Ï'll call  you later then". I insisted on speaking to his manager immediately. He said the manager was busy with another call. I said "get another manager" (I've worked in telemarketing and even the smallest ones will typically have at least 2 managers). He hung up on me.

For some reason, call display showed "yali16".

This number came up on my phone with the Id yali15. He claimed to be doing a follow up call for some gift thing. Asking him a lot of questions about if he is a telemarketer and what he is doing makes him antsy and he will be in a hurry to get off the phone. So much for the "do not call list". If anything we have received more telemarketing calls than before!

scum bags..i called them and told them me and my crew were going down and bust a couple of heads..they got real scared..they phone again and i promise u me and my crew  will pay a visit 2 them and offer them a deal they couldnt refuse..

Call you - man with thick accent - you have won a vacation prize.
It is a scam.

I received a call from this guy who is well described earlier in this discussion thread.  I quickly recognized were the call was going and said "not interested" and hung up.  He actually called back, blocking the caller ID, and said "did you hang up on me b***h" which I responded with ... hanging up again.  

Thanks to all for capturing details and introducing me to this website.
