Flipkart — Laptop fraud

I have recently ordered a infinix inbook i5 11gen from Flipkart on 24th may and i received the laptop on 29th may.
Laptop has manufacturing defects keyboard is not working and lcd light leaking issues.
I have raised a replacement request to Flipkart on 30th May
They give me time of 10 days for replacement.
Flipkart app shows 15th june is replacement date.

On 12th june seller's (BUZZ india) cancel my replacement request.
When i refresh the page new replacement request raised automatically and it's shows 30th june as the replacement time.

They are doing fraud with us in name of replacement they delay the replacement date.

Please help me sir for getting my refund i don't want to replacement because they are doing fraud they automatically cancel the replacement request and delay the replacement date
Does any replacement takes a month.

Help me sir I'm a student and this type of fraud by reputated ecommerce company very hurts.
