Not really understanding the source of your ire, but you may want to check your facts. According to the Electronic Code of Federal Regulations at ecfr.gov Title 47, Part 64, §64.1200 Delivery restrictions:
"(6) Maintenance of do-not-call lists. A person or entity making calls for telemarketing purposes must maintain a record of a consumer's request not to receive further telemarketing calls. A do-not-call request must be honored for 5 years from the time the request is made."
US Pharmacy; they're in India so they don't pay any attention to the do not call list. I've been polite; rude, answered as if I was in a neighboring cube and even answered using the name of a police commissioner' s office near their base of operations. Now I just reject the calls. But once when the guy asked about my last order of Cialis I told it was great and the best weekend his sister ever had.
These folks will NOT stop calling and they are selling RX drugs illegally (without a prescription)!
They use spoofed numbers but they can be stopped by simply eliminating their accounts receivable dept. From being able to receive credit card payments. A sting operation can find out all the info. necessary to do just that!
