I recently contacted a restaurant where I had a bad experience, and a manager got back in contact with me. At the end of the email, they said:
I would very much appreciate the opportunity to speak with you personally to address all of your concerns and regain your confidence in our ability to provide you with a great dining experience. Please feel free to contact me directly at (555)123-4567 or by email at firstname.lastname@example.org
I'm not really comfortable making phone calls, so I am sending an email response. But it just feels much less like "speaking with me directly" than a phone call. How can I politely inform the person that if they still want to talk, they can call me instead?
