Rudeness of staff members at pharmacy - Consumer Complaint for Clicks Store - Head Office

I was in a line for like more then 5 minutes waiting for my number to be called I got a ticket to fetch my child prescription when they called my number I got to the till they said they had called my number 3 times and so she has to help someone else.... So I say no it's fine.she can help someone else then when it got to my turn then she said I took the wrong ticket for prescription and that I have to go back in the long line refusing to help me... Normally when I go to clicks I take a ticket for fetching my child prescription the staff is absolutely rude no way of talking to a customer.... I am so disappointed in greenacres pharmacy clicks
