I am very sorry that you felt your experience with Top Hat Chimney was not a positive one. I can't really comment on the chimney sweeping appointment, except to say that our technicians are WETT certified, and have been with our company for many years. I know that they take great pride in knowing that they are doing a thorough job for the homeowner. It is quite possible that the chimney was not very dirty and required less time to clean than is usual.
As far as the quote for replacing bricks, we do offer qualified brick-masons for all of our repair work, and of course must charge for their time and material. Even though 3 loose bricks doesn't sound like much, it can take a fair bit of time to repair it properly (especially when working on a chimney 30' off the ground).
I really hope that you will change your mind and try us again in the future, so that we may have a chance to win back your patronage.
