Business and trust lost

I received a call from someone from the resolution department on Monday 8/12, was promised a callback by Tuesday 9/12. Its now Wednesday the 10/12 , and to no avail . No call , no feedback nothing . As I stated to the agent. Please dont take 3 weeks to reply to me, she laughed no no I wont . This is nothing new , Miway just doesnt give feedback period . Well it leaves me with no choice to do what I have to do . And this is not about them not honoring the additionals of my original claim , as lets be honest dragging their feet , just says they dont know how to just come out and say we will not be honoring it. But it boils down to the lack of communication skills . So I shudder to think what happens if we have a bigger claim, God forbid....as I have 4 cars currently insured with MiWay .....
