Disgusting Service from Chatsmed Hospital

I took mum to be admitted on 1/06/2020 as arranged by her Nephrologist. We were screened at the Covid station and sent to reception at 12h45. Nobody acknowledged us. I attracted Snes' attention after a while, she asked us to wait. At 13h45 an admission clerk assisted me. A Trauma chart was made, I had to take patient to Covid Tent for test. Testing was done on the outside in public view. I was back at reception at 14h20 and advised Sne that testing was done. She referred to the admission clerk who was busy with another patient. The clerk appeared to be asking her to assist and Sne refusing. The clerk then requested that I wait until she is done with the other patient. At 15h00 I approached Sne again. Mum was really exhausted and anxious by then. She was not apologetic and told me to wait as requested by the admission clerk. Told her I was disgusted by their service (Authorisation from Medical Aid was sent to my phone by then). She referred to the admission clerk, made some photocopies and called for a porter to transfer the patient to the ward. Porter stood by patient waiting for instructions. I gave him the file lying on the reception counter and showed him patient needs to go to D ward. A complaint was e-mailed to *** the same evening. No response has been received to date. On 1/07/2020, I phoned the hospital to request statements. Darren informed me that the systems have been off-line for a while. Must call again the following week. Also complained about my e-mail being ignored. He said e-mails were also affected. Suggested I e mail Dennis Young as he was able to access his e-mails. Complaint sent to Dennis Young on 10/07/2020 and no response received to date. I also received medical aid statement and bills reflecting non payment by medical aid due to "no authorisation being obtained" for certain procedures. How can the hospital proceed if no authorisation was obtained? Totally disgusted.
