Terrible calls Centre service, wait for hours and then they just hang up and you have to start from scratch

I called Dischem this morning because we needed to do a rapid antigen test. We were categorically told we did not need to make a booking for the test we could just "wait in the queue." We then arrived and were told we would not be seen without a booking - the nurse was very rude. After returning home we attempted to make a booking by filling out the form online. This did not work as the form would not allow us to submit (kept giving errors). We then spent 35 minutes waiting for someone to answer our call on the helpline in order to make a booking as the lines were busy. Finally we got through to someone who said we would need to speak to the clinic. They put us through to the clinic who then HUNG UP on us. I HAVE WAITED FOR 40 EFFING MINUTES just to get through and then. you HANG UP!!!!! I must now start this entire process again and have gone back to being number 40 in the calls queue. Who the **** is paying for all the airtime I am wasting being transferred from one useless person to the next because I cannot just directly call the ****ing branch that I actually want and speak to a ****ing human being who knows what they are talking about. Disgusting.
