Cpap machine incorrect claim, still corrected since last year

No claim have been captured on my sleep apnea machine. Its 02:49am and again I cannot sleep, because my machine is broken. But does discovery care... wrongly captured that I had taken a machine. The company send a letter last year to notify discovery that a full refund was done. To please correct & update my details. But no.... months later I am still suffering with chronic sleep apnea a machine that doesn't work and a mask that's broken

Extremely disappointed... I am on a extremely top plan an this is how I get Treated I pay a **** load of money every month for nothing
