Walgreens

I try to order my insulin and keep getting messages back on my cell phone, my insulin is delayed? Being a type 3 diabetes, means I had most of my pancreases removed and require insulin daily. So now I just about run out of insulin and I drive back to walgreens and talk to the pharmacy person, he tells me I can not get any insulin because I already received my prescription in november 2020. I looked at my records and it was september of last year. It turns out walgreens just creates fake prescription records and bills my medical insurance. It this fraud?
