i agree with whomever said that you need to talk directly to the vet, and not assume that your letter (return receipt or not) actually got to her. i found out the hard way that human medical docs are often incredibly unaware of what their staffs do and say to patients--and they never find out unless the patients speak with them specifically.
good vets ARE hard to find, so i'd be wary, too, of tossing one because of their staff--just refuse to work with that tech, period. you may not be the first person to have had a problem, but they'll never know if you don't tell them... MC
