How should patients deal with surgeons and staff who will not call back or answer questions pre-op, especially when out-of-town?

I scheduled PS w/ a MD who cancelled my surgery because I "called the office too often and asked too many questions". I had 4 questions that the main people couldn't answer, but when transferred, - vmails were unreturned. I was traveling & had to prepare based on my prior PS experience. This is happening again & I have 1 open question. I was told twice I would be called & they never did. 2 other docs were just as bad. For 10k, this is not acceptable. What is their problem? What should I do?
