I don't care where you are from, you will not speak to me or anyone else like that

I know people come from different cultures, different backgrounds, different countries.  Our country is a hodgepodge of so many different kinds of people.  I myself have friends who are originally from the Middle East, United Kingdom, Central America, South America, Greece, Japan, and a few other places.  My point is when you are brought up in other places and move to a new place sometimes there is a culture shock...a time where you have to adjust and that's fine. 

My problem stems from people who have no respect for other human beings...especially women.  I know there are countries...cultures out there where women are thought to be below men.  They have no rights, they have no say, they are objects to be owned.  I don't like it but I know it exists.  BUT if you move yourself to a country where women have rights, you CANNOT treat them like you did back home.  You can't own them, you can't control them, you can't treat them however you feel.  You are in a new place, respect our culture.  And I am not being an @$$hat about immigrants (legal or illegal), I know very well there are full bred American men who treat women like dirt but it is frowned upon...usually. 

Where is this coming from.  Weeeeeeeeeeeelll I may have been on the phone with a vendor, calling on behalf of my client.  My client was billed incorrectly and I was calling to get it fixed for them.  The following conversation occurred.  It was 100% awful.  I almost can't even believe it happened.  And no it is not exaggerated, I wrote down most of what was said because I have to report it....... 

Man:  *in a thick accent* Hello, thank you for calling _______.
Me: Hi, I'm NOLAGurl with ______, calling on behalf of Department of _______, may I speak to a manager?
*silence*
Woman: Hello?
Me:  *I explain who I am and why I am calling*
Woman: Oh sugar, this isn't my business, I just work here.  You need to talk to the owner.  Hold on.
Me: K...
Man: WHAT!?!
Me: *slight pause* Hi again...who am I speaking to?
Man: F**K you, why you call me and no know my name?!?!?  You no know me why you call me.
Me: *taken aback* Sir, I am just trying to verify who I am speaking with
Man: You shut your stupid face
Me: *thinking* what the f**k is happening *said* Sir, I am with _____ I am calling on behalf of my client, Depart.....
Man: *cutting me off* You have no right to call me!  I have my papers, you have no right!  You...f**k you and your mother.  Don't call me again!!!!!!!!!
Me: *getting mad* *staying calm* Sir, I am just calling to fix...
Man: Shut up, just shut your f**king face. 
Me: Sir, you are not going to speak to me like that
Man: You have no right!  I lost my wife.  It is your fault!  She did the insurance it is right!  What you do now?  I lost her!!!  She isn't here why you call me!??!
Me: *as calm as possible* Sir, I think you have me confused with...
Man: Don't f**king tell me anything!  You shut your stupid face!
*silence* *heavy breathing*
Me: Sir, I am sorry about your wife but that is not why I am calling.  I am not trying to sell you anything or get anything from you.  
*he starts yelling again in another language*
Me: *talking over him* My customer went to your store, you billed them incorrectly and I need to fix it.
Man: F**k you and your lies.  It isn't about the insurance, I have my papers, I did it all right.
Me:  I am not calling from the State, I am calling from _____________ to fix an error...
Man:  You fix nothing!  I did everything right!  I have my papers!  You never call me again! Not like this!  She is gone and you have the *word I don't know* to call me.  Call me now?!?!  When I lost her!  Do you understand you *another incoherent word* b**ch.
*woman in background saying I don't think that's why she is calling*
Man: *to his employee* You shut your stupid face!
Me: *still shocked a bit* I will say this one more time.  You will not speak to me that way.  
Man: I will speak to you and your c**t in way I want!!!!!!!
Me:  *final straw, deep breath* Okay, if that is how you feel.  If you do not want to help me help you I will direct my customer...all my customers to no longer use you business for their needs. 
*yelling again*
Me: *Talking over him* If you insist on not fixing this error I cannot in good faith send my clients back to your business.  Have a nice day.
*yelling things I wont type*
Me: *click*

Now you tell me what I could have possibly done different besides hanging up sooner.  I was nice, I was calm, I was professional.  He was mean, hateful, threatening.  I do not allow people to speak to me in that manner but I was trying to be a good little worker and get him understand who I was.  To me it sounds like he is in trouble with the government and thought I was calling to...I have no idea.  I was literally calling about billing error that was under $2.00.  It may seem like nothing but I have to get it fixed...
