Flipkart — Not returning money

I ordered Realme 8S 5G from flipkart on 15th April 2022 in exchange of MIA2
(Order id - OD[protected] which cost total Rs 17101 ( Rs 9501 paid from Flipkart Axis Bank Credit Card + Rs 7600 MI A2 Mobile exchange ). Due To Damaged Product i replaced my new mobile Realme 8S 5G and got new Realme 8S 5G (Date - 27 April 2022) but again i got damaged product so i contact with flipkart customer care and initiated to return this product and refund my money.I returned this mobile (Date - 30 April 2022). Flipkart told me that your refund amount of Rs 17001( Rs 9401 in My Flipkart Axis Bank Credit Card + 7600 by Flipkart Gift Voucher ) will be credited on or before 6th May. I Got refund of only Rs 9401 in my Flipkart Axis Bank Credit Card but i didnt got Rs7600 For exchange of Mi A2 past 10 days. Everytime i connect with flipkart customer care they always told me that wait, dont worry your money will get credited, always they give me different date but never credited my amount. Please take this issue as serious concern and please provide me the refund from flipkart as soon as possible.
