Who called from 5597510121

Its for some insurance company and apparently they called from 10:30 in the morning and most of the day, my fiance and I have been ignoring it.

It comes across as unknown and it is a solicitation..

This number keeps calling me but when I answer I get no response.

I've been a call from this number for WEEKS and every time I answer there is no one on the other line...today I waited for 20 seconds to find out who it was and what they want and it just hung up.  I tried to call back and it says "I'm sorry, extension 500 is unavailable.  Please leave your message at the tone."

This is a call center.  On Sep 19 2012, the CSR called me on behalf of Premier Healthcare.  When I replied that I already purchased health insurance from a different company, she hung up on me.  Someone desperately needs phone training!
