Hell YES change your audi and do this immediately, you have no time to waste on other people feeling and the CI or hearing aid is all about you and only you, if you don't like your audi or dr change them, they need to learn the etiquette of communication if they can't let them get FIRED, why would you care, this woman will find so many jobs opening for her, you are the only one will get hurt.
I had same experience with my hearing aid audi, more than one were so so, never liked them until I landed on one 8 years or more back and would drive 40 miles one way to see her even for the tube problem, now when I had to get my CI I went to top CI center in Los Angeles but didn't feel that the dr (who is pretty famous) was for me, he was so arrogant and talked to me for 30 seconds about the CI surgery and kept the door open like he wanted to jump off outside any second, I had to travel to Baltimore, MD to Johns Hopkins and get my CI and follow ups there, yes it cost me more but I couldn't be happier, I now pay a big CI success story due to this wise decision I made.
If the CI dr or audi are not up to your standards fire them and go somewhere else, if you can't go somewhere else then ask for a new different audi until you like her/him, remember the CI will need a lot of mapping unlike hearing aids the mapping is grueling process and needs a nice and an understanding audi if this one can hardly smile or communicate now, how do you expect her to act when you complain about some weird sounds you are hearing with your CI or the fact that the map is not right
Take your time please, do what best for you.
