Very angry and Disapointed at Miway insurance

I reopened my policy on miway insurance and I find out when viewing my policy on the app that they added another car that I did not insure and they put a price that I didn't agree on. I made calls to amend the policy the agents are busy telling me that they escalating the matter to management and they will call me back, I keep on calling and I'm still given the run arounds and I am still waiting for a call from them. their service Is very bad they cant take care of or make means to keep clients I am very angry and disappointed by this insurance company
