When are customers entitled to ₹100 per day for delayed refunds?

Under RBI rules, customers may receive ₹100 per day as compensation if refunds for failed UPI payments or ATM withdrawals are delayed beyond the prescribed deadline. Failed UPI transfers must be reversed by the next day (T+1), while failed ATM withdrawals have a five-day deadline (T+5). For a transaction on October 18, these deadlines are October 19 and 23, respectively.
