Rude, unhelpful Nurse - Century City intercare

Very angry and upset with the service received by a Nurse at Intercare Century City this morning. On Tuesday 16th, I phoned Intercare and asked if I could come with my young children for flu injections on Friday 19th. Was told yes, I can just come and no problem, I then phoned again at 9.15am today on 19th to double check and was told yes, the nurses are there and I can come with my children for flu vaccinations. I arrive there at 9.45am and checked in at the front desk and was told they can help me. The nurse spent the next half an hour avoiding me (could not get her attention) so i waited patiently - after some time, i had to call out to her as she was walking past to ask if I needed to fill out any forms or anything for the injections that she had not said anything about to me yet. By this time, my children were getting very restless (bear in mind I have had to psyche the kids up to go for injections in the first place!). When i called out to her, she huffed and puffed and came over to me and looked very irritated and said that she is the only nurse there today and she doesnt have time to help me. Firstly, she must not make it my problem that she was clearly so unhappy to be there on a public holiday, secondly the place was practically empty so don't know what she was so busy with, thirdly - could she have not told me when i actually arrived that she wasn't going to be able to help me and the children, fourthly - her tone and manner was rude and unpleasant like I was bothering her by being there. i wont be using the facilities at this Intercare again and will rather go to Dischem for any wellness, travel or flu injections etc. She completely ruined my morning by her manner and would suggest she looks for another job where she doesnt need to interact with people (including young children!).
