mckesson / amgen Told me that Enbrel would be free of charge. for six months. Scottsdale, Arizona

I have severe Rheumatoid Arthritis.  In search of a drug to help my condition, my doctor told me abot Enbrel.  I was given a card and told to call this number on the card 1-888-436-2735 and spoke to an Enbrel representative.  I was told that this drug sells for about $1700.  I told her that I could not afford it.  She said with that card Enbrel would be picking up the tab.  She said the first six months were free and only $10 a month after that.

I received my first dosage in the mail without a bill or invoice.  So i figured they were doing what they said.  In total i received three shipments without any paperwork.  Yesterday I received a statement from my Insurance company.  It said that IO had exceeded my max yearly payout on my prescription plan of $6500.  I called my Insurance company and over half the charges were due to Enbrel.  What happened to free.  Had I known this up front I never would have tried it.  Now I can't afford my other prescriptions.  I only make 20k a year and with my husband out of work its hard to make ends meet.I feel this Enbrel is a total scam that is taking advantage of the elderly.   Please help!
