Afrox Customer Care couldn't care less

Due to administrative errors Afrox have been charging me for months for two medical oxygen cylinders that I do not have. When I have exchanged cylinders, the office has not shown that I returned an empty one. Repeated e-mails to Customer Care (what an oxy*****) have never once been answered. Phone calls are answered and promises given to check. I have asked repeatedly for them to check two things. Firstly, the security guard at the Epping Depot checks what you bring in. Asking for these logs would show that I returned cylinders. Secondly all cylinders are registered. they know the two cylinders that I have and can check in their system what cylinders they think that I still have and must be elsewhere. This is just another episode of Afrox's inefficiency. This ranges from the emergency weekend delivery driver switching his phone off. This is medical oxygen that keeps my wife alive. Or closing my account (even though I pay cash for the exchanged cylinders) because Afrox failed to actuate the debit order.
