WHAT IS THERE PROBLEM!!????

Okay so my neurologist has been trying to get me into the neurosurgeon for like the past month. Every time they send the referral it ends up that they don't take my insurance. Wouldnt you think that you would check to see the place that they want me to go to takes my insurance???  This has happened twice already. I should have been in to see the neurosurgeon and have my date set for the VP shunt surgery.  I should not be suffering this long with the medications not working and giving me horrible side affects. I almost was admitted to the hospital this past weekend because the Diamox that I am on made me extremely dehyderated. I ended up calling my insurance company myself and getting the names of the places that take my insurance. I am doing there job, thats what they get payed for. They acted like it was my fault that none of these places were taking my insurance. If they would have done there job in the first place.... this wouldn't have happened.
