I booked a call on 27.09.2023 after 6-7 days the technician visited, the technician checked and found that the motherboard is bad.Since my laptop is not complete for 1 month and the machine is due to manufacturing defect, I am asked to exchange the machine.As no reply from service center. I book call again they said will be informed within 2 days also as no reply, then i informed Great Eastern , Deller said machine will exchange. The machine to has been bad for 17 days and still no solution. Yesterday 12.10.2023 After contacting Deller Service Manager Manas Banerjee Sir was contacted. Manas Banarjee Contact No - 7003858622.
