This is for everyone who hasn t received their insurance information. I called and they gave me what is supposed to be my member number. I have called about 10 Doctor office and they told me that if I don't have a physical proof of insurance I should think twice before using the insurance because at the end if I go to a Hospital for something major I might be liable for all charges since I only have a number which is supposed to be an insurance but it doesn't prove that I have insurance. IS THERE A LAWYER READING THESE. I BELIEVE THERE ARE MANY OF US IN THE SAME BOAT FOR A COLLECTIVE EFFORT TO CLOSE THIS COMPANY. I paid them for the first month of insurance and I haven't paid the following months because they do not send the paper work. Every time I call, they tell me that the paper work is on the mail but it's been three months already and not even a bill.
My biggest problem is that I don't know if I can apply for another insurance company and if I do Preferred Medical will send me a bill for the months I haven t paid and I'll be liable to pay the months I haven't pay.

Any advice?
