extremely unfriendly, unwelcoming, uninformative and not willing to help nurse

I went to clicks valuemart on the 23/10/2019 between 12:45-13:00. I went straight to the clinic. I know to consult there you need to have an appointment, I went to findout a few information before setting an appointment. The sister who was on duty was extremely unfriendly, unwelcoming, uninformative and not willing to help. When i got there there was no one, I told her i came to findout a few things and her first words to me was shes waiting for someone she has an appointment and nicely i told her ill leave as soon as the person arrives seeing that she was not busy with anything. For each question i asked her answer was" i dont know you need to call the clicks call centre". Whats the point of her being there if she doesn't know anything about her job?! I felt clicks so disappointed and shocked. This is my 1st review ever coz i felt it doesn't make sense for someone dealing with people s lives not to be informative about their job. and also someone dealing with people not to have customer service.
