Annoyed....dr vs ins co

I was informed i was suppost to get my surgery yesterday the 26th of oct, so i started my liquids on the 19th all went well lost 6lbs. When i called my drs office on the 24th to see where we stand and if we are a go for the surgery on the 26th she told me that she hasnt heard anything yet from my ins. co. So i took it apon myself and called my ins co and asked if they rec my paper work n to see whats going on n they said they just rec my paper work on the 21st of this month n it can take 10 to 15 business days to see if i am approved. also, the reason they rec my paper work so late was bc the ins co internal fax wasnt working so this was apperently going on since the end of sept beginng f oct. Also im back on solids, bc i couldntdo the liquids knwg i didnt have to so that only lasted 2 extra days.I realllllly want to get ths surgery, bc when i lost only the 6lbs from doin the liquids i started to feel great. But im becomming very impatient!!!!
