Bad service

Bad service: at the Phodi clinic today: I received very off hand rude service. My email regarding icd10 code were ignored I was sent an insistence that I pay (and did) , in error, and which I was now told to ignore. I was instructed to tell Huawei that its phone (and it's default settings) were faulty because their app does not work thereon. I have previously reported this problem- the people in the office were blissfully unaware of it.
