VITALAIRE GROSS NEGLIGENCE

My mom suffers from severe emphysema and this is not the 1st time vitalaire has ignored our requests to replace a faulty oxygen machine which Bestmed med aid pays for monthly from her contribution. The next step will be a ventilator that is how severe her emphysema is.today i sent an email to janie Senekal, Karin Zaaiman,vitalaire and Bestmed at 5:50 am as her oxygen machine needs to be switched off every 20 minutes in order for her to get oxygen. No reply from any party.After calling vitalaire twice i received a ref nr and was told that the machine would be replaced today. It is now almost 10pm and the machine is not functioning properly. Her oxygen cylinder is running empty. Who will be liable if something happens to her?VitalAire or Bestmed or both. Absolute pathetic service from this company. They don't care about the patients. To them it's about getting paid from the medical schemes. The public needs to be made aware NOT to use this company ever. Management refuses to get involved.She is 80 years old ,do you want your loved ones to be dependent on people like this?
