Prescription Hope Inc Pre Hope charged me $100 for a service fee when I did not receive the medications. Stuart Florida

Prescription Hope charged me a service fee without sending me the medications.  They claim I did not send documents when I certainly did.  They claim I owe them $100 as I didn't cancel one day before they said I had to.  There was NO information on why the meds did not arrive for four months.  They will not allow me to talk to a supervisor to plead my case.  Why should I have to pay them a fee when I did not get the medications.  Then they threaten to send the bill to collections.  I just want fair treatment.
