Just hand off a call with paypal

I have a verified business account and want to set up the PAYPAL Express Checkout. But I have no API signature...I searched on this forum, saw a post stated that we should call paypal and paypal will reset something on our a/c to get the 56-character API signature code. So I called PAYPAL 1800 number...

The customer service knowing nothing about their products and asked me to spell 5 times for my short 4 numbers length domain.... then said to me:"I couldn't understand the way you speaking..."make me feel that I am a fool...

Does paypal re-located their customer service to overseas?
I just couldn't understand her English, very very hard to communication.

And she only give me a web link..paypal.com/mps, ask me to find a solution by myself. I visit that link...it's actually a US's site..so I ask do I have to call USA or email?Why there is no department to support the API related question in Australia.....No matter what's I said, she just keep saying that what her supervisor told her...

After a long talk my problem remains unsolved...so I decided to ask here..
So all Australian paypal customers have to call USA PAYPAL to get the API signature?????I feel so unbelievable...
