Samsung — Pink tint on bottom of screen

Address:

Chandigarh, Punjab

Sir i had bought an galaxy s6 black 32 gb on 7.06.2015 at samsung exclusive showroom elante mall chandigarh.The phone had pink tint on the centre portion of the screen.Samsung care centre sector 22 chandigarh checked the phone and declared it defective.So i was given D.O.A certificate.After that the next phone purchased had the same problem.Now the pink tint is present on the bottom of the screen.Again went to service centre but they refused to acknowledge the problem.They compared my phone phone with another s6 which had very less pink tint which is acceptable but my one has noticible pink tint on bottom portion of the screen which is not acceptable to me .After paying a hefty amount for a flagship samsung expects me to continue with such a screen is out of question.The service centre does agree to the pink tint as a problem but they are not giving in writing on a piece of paper that a pink tint presence is normal.I therefore ask you why they are not giving in writing. I do understand that every display is different and not the same but my question is why does a customer has to accept a phone which has manufacturing defect in it.Slight variations is acceptable but not to this extent.So kindly please look into the matter because I have gone through a lot of trouble Thank you
