WORST SERVICE EVER!!!!!!

My mother is 76 years of age and is on 24hrs oxygen through the state with Vital air, on the 11th of February 2019, I called and requested her machine to be checked and her back up cylinder to be replaced due to the current load shedding and that the machine is faulty. It does not supply enough oxygen. My mother is suffering tremendously to get through the day. On the 12th of February I called again as no one had responded to my request to be told by Zandi that the order was not placed. She then placed the order as an emergency as I explained to her that we are experiencing quite a few power outages and that my mom does not have any oxygen in her back up cylinder. She confirmed that she will immediately log it in so that someone attends to it. I tried calling at 16h00 on the 12th of February again as no one has visited my mom yet and there is no answer at all. Today the 13th of Feb, I called again and was told by Corlea that their systems were down but that she will call the nurse immediately to attend. He is busy in Sebokeng but will visit today. I followed it up through out the day, only to realize by 16h30 that no one answers my calls and that no one will assist my mother today either. The emergency number is NOT an emergency number and it seems that every person that I talk to, just take my call and does nothing about it. We use to have brilliant service from Vital air and the nurse use to visit every two months. Since she resigned in September 2018 we have not seen any representative from Vital air. This is truly very worrying. That is the reason that the machine is faulty and that she ran out of oxygen in the back up cylinder. I will take my mom to hospital this evening to get some proper oxygen. THANK YOU SO MUCH VITALAIRE - Let me just take a deep breath.
