Client can’t find good legal help anywhere

Me: Have you sent the settlement check yet?
Client: You never told me to.
Me: Yes I did.
Client: No, you never did. I WOULD REMEMBER IT.
Me: I sent you an email on December 10th. At 9am. It was one sentence long. It said "Please send the settlement check to my office immediately"
Client: I never got that email.
Me: Yes. You did.
Client: I think you are mistaken. I know I never ever received it. I would have responded to it.
Me: You did. Your exact words were “I’ll do it.” Would you like me to send you a copy? You’ll notice that my email is copied in your response.
Client: Oh.
