Refund for Mistaken Transfer

I am writing regarding a mistaken transaction I made today through my Fampay wallet. By accident, I transferred 150 ₹ to the account of Mr Dinesh (ID: rt9068***@mvhdfc) instead of the intended recipient. The attached screenshot from the Fampay app clearly shows this transaction, including the date, amount and transaction details. As soon as I realised the mistake, I contacted Fampay customer support and explained that this was an accidental transfer. However, I was told that I would not get any refund, which left me very upset because I am seeking help to correct an honest mistake. I kindly request that Fampay review this transaction and process a refund or reversal of the 150 ₹ that was sent to the wrong person, or otherwise assist me in recovering this amount. I expect clear information on what can be done in this situation and a fair resolution to my problem.
