Samsung A22 5g— Samsung

26 Sep,2021
I purchased a Samsung a22 5g mobile from Flipkart, delivered on 15th sep 2021. I opened the mobile and activate eye comfort shield. Now all black colour objects become brown. I asked for refund or replacement. They send teachniacian 2 times. Teachnician conformed that this is the feature of mobile and can't be replaced or refunded. But in no where in flipkart is written this feature of mobile. Now they are refused to return my stating that" return policy is as per seller. Kindly help me to return this mobile
