"dental nurses bad Attitude"

my mother had an appointment at 9am. A dental nurse had come over to my mother & I saying they have not got the results that we were expecting to discuss today, as QE hospital have not written up the report & told me to come back after an hour. I was really upset and asked the nurse why My mother has been called back if they haven't got the results. I told them that this is not right & not my problem to why they don't have the results. The nurse turned replied back "that's not my problem either" with attitude & stared into my eyes. I was really shocked with their attitude, I could not believe they were allowed to speak to me like this. Is it not their job to ensure they have the results a day before or so? Or at least call us & cancel? Instead of us turning up. Why do you have nurses working their that can't speak to the public properly & give attitude? I also explained to them that I will have to yet again pay another £14 for parking if I have to wait any longer. I ended up up waiting 45 mins extra to be seen. I have previously waiting 3 hrs at this dental hospital on a separate occasion. I can't express the disappointment. I contacted the customer service team last time & I got a call back saying they will look into the issue I had but I haven't heard anything back. I strongly recommend people not to visit this place.
