Dell India — Unprofessional behaviour of the service centre regarding a complaint lodged two months ago

Since I have purchased my new laptop in July 2021 there has been recurrent problems in it . From the previous three months I have been constantly complaining about the problems in my new laptop like keyboard not working, the laptop not turning on etc. to count for a few .However, everything is falling in deaf ears as the customer support panel always say that our case is in procedures and the concerned people will contact us in a few days .However there has been no contact from their end .This laptop is of no use for me as I bought this for my daughter so that she can conduct her virtual classes, unfortunately it is hindering her education as well in this time of pandemic.The details of the laptop and the complaint are listed below:
Date of purchase: 20 July, 2021
