These people used to call me every couple days harassing me on my cell phone, claiming they are a pharmacy and they sell cheap drugs like ambien, painkillers, etc.-at first I thought it was a legitimate pharmacy and ordered some of my regular daily medications through them.  Their meds aren't real- and they caused me (a healthy 24- year old) to have a seizure. After that, they called me over and over and over until I finally blocked their number.  Now, they have somehow gotten my parents' home number, and instead of calling me they call them, harassing them and yelling at them to buy their drugs.  My father is ill and has such awful heart problems that the ringing of the phone can set off his atrial fibrillation- and if my mom hangs up on them they will literally call every minute until they answer, and then the person yells at my elderly parents, screaming at them to buy medications.  It has upset my parents to the point that they want to change their landline number that they have had for 30 years.
