These call do not originate from in the USA so the "no call list" does not apply. They change numbers all the time. Most run scams, others actually sell controlled drugs from the Dominican Republic. You either got on the list because you purchased drugs on the Internet in the past, participate in those scam lotteries, or other such stuff. Don't send money, tell them to send you the goods first. If they are not a scam they will.
Just called me 4xs in 2mins. I've received calls from this foreign pharmacy before. Seems the phone # keeps changing to...WEIRD. Very annoying and I've also requested to be taken off the list.
