I missed this call. Who was it?

I received several calls for somebody else from this number. When I called back, I found out
that it was a collection agency called Global Credit & Collection. I found there website
( http://www.globalcollection.net/Consumers.aspx ) and contacted their main number. They
told me that they would remove my phone number from their files, and they did.

OMG I got this too
shes very annoying and threat people so bad even though i told her that
a person shes trying to look for is not here !
I am trying to find a way to deal with it.

I've been getting calls from this number, too, but I always get a blank message.  I refuse to answer unknown numbers.  However, I know this Ms. Khan - Juanita Khan is her name, from Global Credit.  I found out about her because she started harassing my parents with phone calls two years ago.  My parents didn't tell me about her for ages, as they were trying to protect me from her!  I had never heard of the company before, but eventually found out that an account I had with a different company was now being dealt with by this company.  I talked to Ms. Khan myself (she was very aggressive and rude) and told her to stop calling my parents and to take their number off their files.  She told me she took it off, yet shortly after I got a message from her threating to start calling my parents again if I didn't call her back!  

I ended up talking to a manager two levels above her, who at least treated me like a human being.  I also wrote a letter of complaint and demanded a letter of apology for my parents.  That was over 6 months again, and I still don't have it.  I also told them I would only deal with them in writing, not by phone, and that I wanted her off my account.  I've been writing to them meticulously as I've made my payments, asking for receipts, and the only one I ever received (in January) was signed by Ms. Khan!  I finally wrote them I wasn't going to make any more payments since I had no verification that they were going through, asking again for a <b>written response</b>.  This seems to be too difficult a concept for them, because I just found another message from the company. I couldn't hear most of it, including the person's name, but from what I could decipher, they want me to call back and "make arrangements."  *sigh*

BAHH! She did the exact same thing to me. I just hung up.

I got phone calls ( many many times ) from a woman (Ms Kham, as she claimed).
She insisted my company own her company hundred thousand dollars and tell me to ask my lawyer to phone 905-413-8533. I told her she got the wrong person.  She started to threat me.  Very bad !

Oh and now they are calling from 419-054-1385.

I don't even know who these people are. I haven't had this phone number for very long. The message tells me to call a number with a reference number along with it. They won't tell me who they are or why they call but repeatedly ask if I am (name I don't recognise). I say no, who are you, stop calling etc. They keep calling.
