Poor customer service

A claim ***) was logged in July for a new CPAP machine. After requesting a doctor's recommendation, I'm still awaiting for claim to be processed. I keep following up and they haven't resolved what is their own internal system issue. I spoke to Marcy who assured me that I will get feedback the past Friday, and that didn't transpire. In the meantime, for many weeks now, I'm not getting a good night sleep, which increases my risk for a heart attack or stroke. With pre existing conditions such as hypertension, diabetes, this is exacerbated. This is totally unacceptable as it affects my health, and I am tired during the day as a result of not getting a good night's sleep.
