Flipkart — Laptop defective replacement

Hi, I ordered a laptop from flipkart on 1st december and received the same on 3rd december. The laptop has an issue with the audio headphone jack where the audio gives intermittent static noise and also a very jarring crackling noise. I tried to resolve it on my own thinking it to be a software issue but no use. Then I put a return/replace request on 7th dec and flipkart gave me the date of 17th december to wait for MSI technician visit. There has been no contact from the technician and I am stuck with this defective product. I have paid full amount for an expensive laptop and can't even use it to its fullest. I have again been told to wait till 21st december when its already been 10 days and no response. I am not going to wait in this forever loop where I have to follow up with this issue. Need immediate action on this. Order Id: OD[protected]
