radio code

I have purchased a 2004 opel corsa Gsi.I have been kindly phoning the dealership for the radio code which has been on SAFE mode.but nobody has been able to help me they keep telling me to phone other companies and other places .I cannot understand why such a big enterprise cannot go the extra mile for a customer all I want is just a radio code.it's unacceptable to hear that they only keep radio codes for 2008 model cars and above.so what do I do with a 2004 model opel corsa.I'm not speaking to people of the street.I'm speaking to proffesionals which have failed to deliver.I'm very upset and dissapointed .
