Extremely Bad Service.

In 2016 I was advised by Bankmed to switch to Vitalaire from the previous provider Afrox. Once I have switched over to Vitalaire they have not paid afrox for their services that they have rendered. Now that I want to switch back to Afrox, they want their money from medical aid before I can move over. I have sent a request to ***, requesting them to settle the outstanding amount at Afrox so that I can move there and requesting assistance with the new portable machine. I have also sent them an email stating that I am not getting any joy from Vitalaire's service, and I need them to settle the account with Afrox so that I can move back to them and so that they can assist with the purchase of a new portable oxygen machine. I have still not received any feedback and this has been ongoing since April 2019.
