User: Yeah, we haven't processed.
Agent: Understood. We'll issue a full refund to your original form of payment, and you'll receive the amount within seven to fourteen working days. For security, we have sent a one-time PIN to your registered mobile number. Please enter it on your phone keypad: press the hash key, then the four digits, then the hash key again. Or, if that's easier, you can simply say the four digits aloud.
