[Resolved]  Flipkart — Money not credited to my account

I bought a laptop from Flipkart on Nov 25 2020 . It cost ₹32990 . Due to some issues I wanted to return the laptop . But then I had to wait for the technician visit . But no technician came and I had to wait for two weeks and finally they took the laptop . Then the seller initiated the payment the very same day . It started on 14th December . And then I had to wait till 24 th as the deadline for money to be credited to my account.
But then it didn't happen . I sent them my bank statement via email and they told me to wait till jan 1 to have the problem resolved. I also contacted the bank and they told me that the money has not been credited and to contact Flipkart for the same .
I waited for a few days . And then they extend the date to jan 5 . Then again they extend the date to jan 6. And each passing day the deadline keeps increasing . At first they told me that the issue will be solved within jan 1 . And it kept on increasing. Now it's jan 7.
I have waited for nearly a month and I don't have a laptop with me because Flipkart keeps playing with my money like this . I think the transaction failed from the seller end . I don't understand why Flipkart treats it's customers like this .
