My wife has had filled monthly prescription filled thier every month now for a few years. It has always been around $435. Last month they said it was only $100. We were amazed mostly because We do not have health insurace. We always pay cash up front. The first time the prescription was $100 we brought it to their attention. They said they ran it through 4 times and that the price was right, and that they could not come back and ask for more money. So the second time same thing. I paid and have the reciept correct amount of pills and the right description. Today, three days after filling they called. They were not polite at all actually quite the opposite. They said they wanted the $300 plus difference or the medicine back. They why the are handleing it I would rather pay a lawyer than them. Do I legally have to pay them? I have new talked to the district manager who would not even talk to me and told me to email him.
