I bought my phone on 29/12/2017.phone got a charging issue so i submitted my phone at authorised service centre durgapur on 29/08/2018.( Microsys, Durgapur).They called me on 5/09/2018 and asked to to take my phone back.I had arrived within an hour,to be delayed by another 2 hours because they hadnt even tested the phone yet.After waiting for 2 hours,I finally asked them to give my phone back.They immediately gave me back my phone.i went to kolkata(being a medical student there)From the next day itself,the phone just switched off on its own and heated up.tried charging the phone,but the charging indicator wasnt working.14/09/2018 I again went to the service centre in durgapur.staff at service centre about display had problems thus needed repair.Then they said my phone was not in warranty anymore since it had scratches and forcefully made me write a acknowledgement about the damage telling it was a formality and my phone will be repaired.They had checked the phone on 29/08/2018 and there was no problem. There has not been any misuse or damage from my part either. the damage has been caused by them as they hurriedly tested my phone and carelessly handled it on 5/9/2018.They asked me to send my invoice on 18/09/2018 over whatsapp and said my phone will be replaced.tollfree care said that spare part has been ordered by service centre and they will repair my phone as soon as the part comes.the manager at durgapur said no part has been ordered and the tollfree support is lying and my phone will be replaced in a month.I am very displeased by the customer service and I really want a replaced phone since obviously the technicians here in durgapur are not doing their job and is lying continuously
