Can I say "my bad" instead of "my mistake" in this context? Or is it too casual?

In this context, it's a little too casual to use "my bad" here. Working in the service industry, it's important to use formal English to show professionalism to your customers. You can use "my bad" when with friends or family. Ex: Whoops! That was my bad. Ex: I'm sorry, my mistake, sir. Ex: My bad. I thought it was next week. Ex: My mistake. I will fix that right away.
