Western Dental Services review: automatic billing updater

I called this office on 10/12/2019 around 1:20 pm for my billing updated. She said can not do that and try to give me another number to call. I asked her if she sure can not do that? I believe she was getting rage and hang-up. To Western Dental. This person is unprofessional customer services. Should i deserve to have service with Western Dental with the kind of very rude and so temper of this kind of person services?
