My restaurant used some ingredients that might not be fresh and a customer is now complaining about the food. What measures should I take to deal with this problem?

In order to address the customer’s complaint, I should apologize and let the customer know that their experience was not up to par with our standard. To make sure a similar incident doesn’t happen again, I can implement an updated food quality control protocol that includes regularly checking expiration dates of ingredients and making sure all ingredients are sourced from trustworthy providers. Additionally, I can offer compensation such as discounts or credits in the form of loyalty points for future purchases.

Sorry for the delay in response. 
To deal with this problem, I would suggest to first check the ingredients to verify their freshness. If some ingredients are not up to the expected quality, replace them with fresher ones and refund the customer. Furthermore, apologize to the customer and offer a discounted/free meal as a compensation. Finally, take steps to prevent similar cases from occurring in the future. Thank you!
