Bad service from claims administrator.

In general, the service is fantastic. There is, however, one exception. The vehicle went into intensive care more that 4 weeks ago. At the time I selected Uber as the replacement. After a couple of trips, I figured that was far too risky and requested a change to a rental. This is now nearly 4 weeks later and a few phone calls with no response, and I still need to use Uber. Calls to Discovery are not returned, even when the person assures me the "busy" claims admin will call me back. So, I'm stuck with Uber. I wonder how Discovery's Medical Aid will react if I get Covid while using an Uber.
