Flipkart — Wallet balance withdraw prior expiry date without notice.

I, dr.Ramesh hold an account with flip kart with the above email id and 7xxxxxxx0x. as phone number. .I was having, in my account the wallet balance as Rs. 863/- which it was stated in your site, lasts till 5th September 2023. (Expired by 5th september'2023)
Surprisingly when the account is opened today(22nd August'2023) ;the wallet balance Rs. 863 disappeared/not found/ withdrawn without notice without furnishing any reason.
My account requires to be restored and check once and find out why a regular and reliable customer has to face this kind of situation (waste of time and money and agony)
Hope flip kart will resolve this issue at the earliest.
