I believe it is from a "company" selling generic viagra and other "medications" without the requirement of a doctor's prescription. No idea as to their trustworthiness.
Calling several times per week, despite my number being on the DNC list and me demanding to be removed from their calls. Does that even work? Do people suddenly think, "Oh, they are persistent with calling even though I made it clear I don't want them to... I think I'll buy something?" Who buys anything from these [***]?!
Repeated calls from this company, now with increasing frequency, wanting to know if I want to buy Viagra, etc. I have asked to be removed from their list, but I believe that the phones are set to auto-dial, and the telemarketers have no control over the numbers called. They only take calls that are answered and then try to sell.
