I appreciate that some conversations require face-to-face meeting, and on occasion, some conversations are better over the phone than via email.
BUT, if I want to engage you as a service provider or supplier, I have contacted you in the first instance via email, then that means that I would prefer a response to my initial query via email. Not a reply from you saying 'please call me.' GAH. Perhaps I have not provided enough information for you to adequately respond, but if that is the case, let me know. Via EMAIL.
Jesus wept. Urgh - totally pointless AIBU but I feel better now.
