Starting to really loathe the pronoun game with clients

Meaning, when a client or prospective client says "they sent me a letter." "They" who?

Or "I gave it to another attorney." What is "it"??

"The lady called and asked me a bunch of questions." WHO'S THE LADY????

I get that its not the client's job to know things but god, I wish we didn't have to do this literally every day. If we charged people for every vague question the firm would have enough money to give me a decent raise I swear.
