Flipkart — I'M complaining about the different serial number on package and on product

On 03/07/23 i apply return request of noise buds VS404 from FlipKart and after somedays i registered for warranty but on filling up i checked on serial number and found that the serial number on package and number imprinted on the product are different before this incident i just return the first product (noise vs404 same product) on getting a defective product . on my invoice there is no serial number . i need refund or return on my product
