What do I do when a WhatsApp customer says the bill total is wrong?

Send the bill line by line, with every price and charge, and check it against your menu. Fix a real mistake at once, and explain a correct total calmly.

• Do not defend the total first. Ask which line looks wrong.
• Send the bill as one list: each item, quantity, price, delivery charge and any packaging fee.
• Check each price against your current menu. If you made an error, say sorry and correct it.
• If the total is right, explain the extra lines kindly, such as delivery or packaging.
• Settle on the fixed amount in writing before you take payment.
