Very rude and violent " pharmacist "

I went to go pick up my script 3 weeks ago from medirite Montana, all went well. To my surprise I got a call a week and a half later from a African lady demanding that I come pay for my medications cause my medical insurance does not cover it, she then passes the phone to a white lady who explained to me that it was a locum who made the mistake and now have to pay for it, I then said that I was given a generic and did not use the medications she suggested that she picks it up she Came to my house on a Saturday afternoon demanding money and not the medication like we agreed on this lady was screaming and shouting at me infront of my house, my 2 year old daughter and my 70 year old grandmother when I walked away she literally ran behind me demanding the cash . I am disgusting with the service I received
