Spare key not received

I bought a new hyundai i10 2017 on the 23 November 2017 and I didn't get a spare key now they all passing a bark to each other they don't know where is the spare key they want me to bring the car for them to do another key. My consent is one where is the spare key since it's a new car I believe it should have came with a spare key. I am not happy at all because they want to do another key which doesn't make sense at all because they spare will still be working on the car, Should the car be ****** they wont be responsible I am sure about. And I did send emails as well to the absa finance just to make them aware. It's either they take their car back or they change the whole ignition and locks so that the missing spare key wont work ever again. My name is Princess contact number ********** 389
