After phoning the contact number on the website to ensure they were able to obtain the correct code for my radio,I purchased a code from this website. This was for my 2004 Corsa C standard Siemens radio. 'Thomas' was kind and friendly at first, and emailed me my code promptly. Unfortunately this code was incorrect (I have entered codes on similar stereos before with no problem). When I told Thomas about this he became very rude, accusing me of having a reprogrammed radio!? And even threatened to contact the police when I informed him I would be contacting my bank in order to obtain my refund. I seriously suggest you avoid this scam of a website, and purchase your codes from a reputable website or local dealership.
