Turned back with 15 months baby because doesn't get paid overtime although we had an appointment and wcarre early

My husband and I received the most distasteful attitude on 3 April 2023 from Sister Doreen Suliwa/Suluwa at Dischem wonderpark. We had an appointment for 17:30 for our daughter's immunization which was confirmed and the sms at hand we arrived 20 minutes before our appointment just to find the doors closed. After several enquired a lady by the name Rorisang informed us that the nurse is in the room. The nurse who's name is Doreen told us that she cannot help us because she knocks off at 5:30(this was at 17:20) she hasn't had her lunch and dischem does not pay her overtime. We had to leave with our baby without her immunization and this was the last day from the window of immunization. The saddest thing is her telling us that she doesn't work all day while we had to leave work early to be there on-time. She was unremorseful and unapologetic even though we had made an appointment. My daughter has had almost all her immunization from Dischem and this was by far the worst service we received. A client with an appointment being turned back with a small child because someone doesn't get paid overtime even though we arrived early. No one could careless about the wellbeing of the baby and were told try tomorrow. This is really unacceptable from such a big institution that we have been so loyal to.
