WOW, Manuel, we are SO glad you are OK ...
It is wonderful that we live in an age that those kinds of life-saving procedures are available ...
You are in my prayers for a full and speedy recovery ...

I don't know what insurance company you have but that lack of response is totally unacceptable ... I worked in the 'insurance field' for 40 years, and that lack of attention deserves a complaint filed with the State Insurance Department:

Be well ...
