Inspiron 15 3511, multiple issues

My laptop is Dell Inspiron 15 3511. i purchased my device via offline mode from dell exclusive store on 17 sept 2021 so 11 months/18 days old.

starting some days device seems to be good but after 2-3 weeks it showed its real nature.

at first its hinges got loosed and i could not even turn it on. for which i created a service by messaging method and the technician arrived and solved the issue. i also even told him to check properly for any issue on my device. it seemed that he checked but

after some days some software issue began in which i could not run my job software and other also even i could not even update my windows.

while the above issue gets solved another trackpad issue arised in which my cursor gets stuck frequently.

after analysis it was discovered that my trackpad is defective the cursor is working fine when operating via external mouse.

and after somedays i observed that my screen edges are elevated from middle and does not touch the keyboard panel (pics attached).

as per me the device is having some major issues which cannot be solved by only replacing the parts and dell is ignoring it. it has some serious issues .

i am a college student and requires my laptop for daily routine works. Regular contacting dell for sevicing are creating barriers in my way of efficiency and hampering my studies.

clearly can be observed the in between the flaps
