VW Radio Security Code

We brought a VW Polo brand new from VW and recently needed to replace the battery. Once the new battery was installed we were requested to enter a security code to activate the radio. On checking the manual there is a spot to add the security code but this was left blank by the dealer. As per VW this is a "security" feature. We need to take to car to our nearest dealer and pay to get our own code back ?!? We own the car, we own the radio, why do I now need to pay for this ? I laid a complaint with VW and they brushed this off stating that this is a security feature and I need to pay to get the code issued.

What a load of nonsense. We own the car, brought it new and therefore own the car and its accessories ! This is a money making scheme , nothing else! I will NEVER buy another car from VW.
