Pathetic service from an admin staff at Netcare Parklands q

I called Parklands hospital roughly 5x last week, I spoke to an Indian lady at reception who advised me to speak to Tobi in regards to finding out further information for a hospital booking. I spoke to Tobi who said she was busy with a patient and would call me back. I had left my number with her. I proceeded to call numerous times thereafter neither did she answer or call me back. She is extremely unhelpful and does not deserve to be working in a job to assist people especially if information required is time sensitive, someone else that values their job would take what they do more seriously. My doctor is based at Parklands hospital, but now the doctor will now complete my surgery at another hospital due to the pathetic service from Tobi and this was time sensitive.
