2012 Polo Vivo Sedan

Since Monday i called VW on ********** 737 to retrieve code for my radio and i was told to call VW Centurion which is the dealer and their phone is ringing with no answer and their numbers are ********** 810. VW Wonderboom they want me to pay R400 just to retrieve a code. My question is if i forgot my bank pin and went to bank just to retrieve it must i pay? and my answer is no,I cant pay to retrieve a mere code.
