I have purchase this handset from amazon on 2ndjuly 2019. I got the delivery on 9th of july 2019. On 9th sept the mobile charging socket has stop working so i have given it to authorised samsung service center in sion on 10th of sept. On 10th sept service center has accepted that the mobile is in warranty and this socket they will replace it free of cost so i have submitted my handset. After changing the socket new problem has started immediately that the mobile could not detect the mobile signal. So the service center kept the mobile and changed the mother board, formatted the ios, try to put upgrade but nothing is working. The problem remains as it is. So on 14th i have contacted the samsung call center for help. Till date i have not received any resolution from samsung. I have escalated the case to ceo email id 4 times but invain. Every time i get a call from escalation desk asking for more time. There is no dead end to their response. Can any body able to help me?
