Bad service and warranty problem

Hi, I have purchased a Samsung mobile star GT-S5233, from almost 12 days and it is mentioned in the warranty " if the mobile has any technical error within the first 14 days from day of purchase it will be replaced with a new mobile",

I went yesterday to get the new one, the customer service and maintenance center refused and they were very aggressive although they gave me a report stating that the mobile has a technical error,

Need your support for such service
