My order id: od[protected]. I received this order (Lenovo a6 note) on 27-jan-2020. Mobile is restarting automatically in startup. I placed the replacement request for this order. Since then indiflashmart technicians visited and he has confirmed that phone has a restart issue. Next day i received the message that "return approved" but after some this time it shows "return cancelled" with reason that issue resolved (Such a liar e-commerce). To this i again put replacement request. After that whishmaster coming but he is not picking mobile because he is unable to getting imei no. To this i again put replacement request. Now they didn't sent technician nor they are doing anything of replacement. All customer executive says our team is working on it. And after replacement policy expire they said that we will not unable to help you because replacement policy expired.
Please look the matter and provide the resolution asap..
