Urgent- please help- Address in Netherlands!?

I would like to check an address in Netherlands,

can someone in Netherlands help me to find out coz they ask me to fly to their office for business. Please help, this is very important to me, your help is highly appreciated.

General contract payment office for Humanatrian Aid Commission
Balen van Andelplein 2c
2273 KH Voorburg
Netherlands
Telephone: 0031-208-908-097
Fax: 0031-847-409-858

I'd like to thank all of you who have answered my question. All of your answers are very constructive & helpful to me. By summing all the answers, I believe its a scam. thank you once again for your help, i love you guys!!

I used to live near that place. It's just another unassuming office block housing a number of companies, none of which even closely resembles a humanitarian aid organisation.

The fax and telephone numbers too, don't match the Dutch pattern. True, 0031 (or +31) is the Dutch country code, but all telephone numbers following the country code should be preceded by the (0)70 area code for Voorburg, which is a suburb of The Hague. The numbers you've posted simply don't make sense in the Netherlands.

I should be very careful with this lot if I were you.

the firts thing I noticed is that the phonenumber is a number in amsterdam, Voorburg should start with 0031-708-908-097, the fax the same, have no idea where that should be. I,m living nearby the address, I know there are some small scale offices over there.
I can look for you, will pass by tomorrow.

there is an other office at that address, 2c does not exist.
hope it helped you.

I also didn't find the address of the office
There is a Housing fund (stock) Voorburg
at the address Balen v. Andelplein 2
2273 KH Voorburg
But nothing at Balen v. Andelplein 2c

Also their telephone number doesn't appear in Google search or goudengids (yellow pages)
