Apple India — Apple Macbook malfunctioning

I had acquired Apple MacBook -Air on 21st February 2020 from Flipkart (Vendor : Sane Retails (p) Ltd) (Invoice no FAB7L[protected] . It was used by my daughter in the lockdown for her online classes. While using she encountered the following problems
(a) The system intermittently got hanged (b) Input audio or Mic issue while using Zoom (c) Not able to catch the Wifi connection (d) Laptop not able to locate the Apple Airpods

The laptop was given to Unicorn Infosolutions (Andheri ) for service under warranty vide job no : MA5845581 on 1st July 2020 with the aforesaid complaints .I got the delivery of the laptop after 15 days but on usuage the same complaints still persist and is a big deterrent for my daughter to continue with her online studies/classes .
As my daughter cannot spare the laptop for 15 days for another service as she has online classes/exams I request a refund or a replacement .
