Bestmed Medical Aid

I have been diagnosed with Covid and I am Asthmatic. I have sat 27mins on the phone to get med aid to authorize a R500 Oximeter machine. I have Benefits in my Appliances. It is needed to measure the Oxygen levels. I have sent Emails to Service and PMB websites Dr has prescribed this machine Surely Bestmed has somebody who realise the Urgency of the situation. I spoke to 3 people this morning. No joy Diskem is awaiting approval to dispense. I do not have the funds to pay for the machine. I am a Telkom Pensioner. Can anybody out there at Bestmed assist me. Do the staff know what to do. To sit on the line awaiting for someone to answer my call, a person must listen a whole lot of advertising. Just waisting airtime. A little bit more effeciency from the staff would be great. They just cut you off, then you are holding on again.
