Levi's India — Black denim premium quality jeans color fade

Hi Team,
I recently purchased black denim premium quality jeans of 6k. Within 1 month on first wash and that too washing inside out fades color and white spots are seen on complete jeans
There is no way to remove those spots.
If leavis premium product is also facing this issue,
then what is use of purchasing premium product from levis
I want replacement for levis jeans otherwise I have to raise a consumer complaint for same
