Samsung India — m30 is faulty and no service

Address:

Samsung service center, bengal ambuja, city centre, Durgapur” PIN-713215, 713215

Unfortunately i purchased Samsung M30 from Amazon on 4th June 2019 but few days ago 4th October i found pink spot on lower portion of my display gradually within 3 to 4 hours the whole screen turns pink and from next day the display gone off.
17th October i went to Samsung service centre of Durgapur “Sansung service center, bengal ambuja, city centre, Durgapur” PIN-713215 and told my story, they first took my phone and gone inside their cantre without any form fill up. After sometime that man came and told me that it will be repaired nothing to worry . after sometime he again went inside and after few time he came out and told me that the screen is damaged and its positioned up side than its original position. after sometime they took my signature in the name of jobsheet or something i never heard of. so according to them my phone is damaged without any sign of external accident . no screen crack no phone distortion nothing but they know that my phone is damaged and Samsung is sacred.if its the reality that a phone automatically spoiled within a month and its the service they always told us then Samsung is nothing but a cheater.dont buy sasung phones.
