Bad service, lack of urgency and unproffesionalism

After writing a review complaining about Vitalaire, the two ladies from the Port Elizabeth office phoned my Mother to ask her why I wrote a complain about them on this site. She was waiting nearly a month for her new oxygen bottle. My mother indicated that they were rude with her and even today when the sister delivered the oxygen she was rude, so mych so that my mother's chest nearly closed. She left with the words, your account of R230 will be send for the delivery. I really have no words for these people and their lack of urgency and respect. July 2019 we had n problem with them as well and I also posted here and only then did they act. They are well aware of my mothers condition.
