Dell - Service not resolved in Warranty

I had purchased a Dell **** Laptop on *st Nov ****.
It had a Warranty of * year in which all system, parts, hardware, software defects would get covered.
On using the laptop there was misalignment of hinges due to it the laptop created a gap upon closing and the display produced a print of the laptop's lower part (Keyboard Section) which could not be sorted out even after cleaning a lot of times.
I had shared all the problems with the Dell support and they agreed to change the LCD screen.
When the Engineer had changed the laptop's LCD screen it was having a defect (yellowish tint display) due to which it impossible to use the laptop as it irritated eyes and decreased the life of the laptop due to full screen brightness and high battery usage.
The Engineer also agreed to the same and contacted the support for the replacement of the part once again.
The company took a month to order the part as it was in shortage due to unavailiblity. When the Engineer replaced the LCd screen *nd time, it was having the same defect (Yellowish Tint display) to which the issue remained unresolved. The Engineer gave a suggestion to replace a new packed piece laptop( either same model **** or an upgraded one) or credit the laptop amount for the issue to resolve.
The same was communicated to the Dell Support team a lot of times and they gave me only one response that their phone support team would contact me. It has ben more than ** days, I haven't received any update regarding the compliant.
Recently, when I had contacted the company is denying over to replace the laptop or credit the amount as it doesn't support their policies.
They say again to replace the LCd screen *rd time which is of no point as there is no assurance if the display replaced can again be defective of a Yellowish tint or can solve the problems.
I have been facing a lot of problems and unable to use my laptop due to the same and there has been a lot of delay in the service provided twice (for the same issue)
