Netcare N1 City bad reception service from Cleo Abrahams

I have had numerous experience at Netcare N1 City with a very unfriendly, unprofessional receptionist. Her name is Cleo Abrahams. She has no way of speaking to patients and staff. This had happened a few times already. I Have emailed Netcare Customer Service and they had forward the email to Netcare N1 City in December and I received and acknowledgment letter. In January I resent the email as I have not received any feedback and said I will take the matter further, yesterday I emailed again this time with no reply or acknowledgement letter. I received a call and another acknowledgment letter after my second email but no feedback or acknowledgment for the third. When I received the call from the hospital l was told the reception manager was off sick and will investigate upon her return. Another week and half has past and still no feedback, no apology, nothing. Netcare N1 City is rated one of the top 20 Hospital by Discovery medical scheme but their reception staff are not very welcoming and friendly. Especially Cleo Abrahams. The manner in which she speaks, her facial expression and her body language is not that of a receptionist at a private hospital and like said previously, I had numerous encounters with her. The manner in which she ask for you documents on arrival is utterly disgusting. She is working the patient and stressed family members not dogs. Even the way she answers the switchboard without identifying herself and when I asked her name she said “you called N1 City Hospital what do u want?” Well I know what number I called I asked for her name not which company I called. she also does not get up from the seat she is sitting in when someone is at the front desk for an inquiry and the count is quiet high and she sits fairly low. Her service delivery is not on yet there are posters throughout the hospital of Netcare Values. What are those posters for if they do not even reply to a complaint. What do I stand to do as no1 gets back to me.
