exsseive calling

company calls me daily. I have asked to be taken off their list. Or put on a do not call list. They just hang up on me when I protest them calling me everyday. I have asked to speak with a supervisor, the man just hangs up on me. He speaks with an India accent. I almost think this man is enjoying harassing me. I have gotten to the point of just laying the phone down when he calls. It is the same person EVERYDAY!!! It is harassment. I wish I could sue these people. I do not know how to get him to please stop calling. Its has stressed me out so much, just because I tried reasonably to talk about getting on a do not call list, then to be hung up on, and harassed the next day by the same guy. Its gotten beyond annoying. If I try to call back to complain the phone number doesn't go through. I have told this man company many times to please stop calling. Why won't the just move on to someone interested in being a customer. Like I said, this person seems to get joy from my feeling of undeserved harassment. I hope someone puts a stop to US Pharmacy's criminal harassment!!
