After sales service of Ford Sucks!!!

I purchased a brand new Ford Figo. Over a year after I purchased this car, i was involved in an accident. The car went in for repairs and the due to this the radio was reset. I then realised that my book did not contain the radio code which I have to enter. I have phoned the Ford dealership where I purchased the car from and they have advised me that I need to pay for the code or bring the car in at a cost. I then emailed the head office which is stipulated in the book provided on 10 November 2015 and still have not received feedback from them. I received an email to state they have received my mail and will contact me in 24 hours. Still nothing! The after sales service of Ford is terrible. WHY DO I NEED TO PAY FOR THE CODE IF IT WAS SUPPOSE TO BE GIVEN TO ME IN THE FIRST PLACE WHEN I BOUGHT THE CAR?? This is not what I expect from a brand new car and after sales service of such an BIG company.
