Thank goodness my Panasonic cordless phone let's me block numbers like this for free. If you have a cordless phone..check to see if it has a call block option and use it.
Claims to be an online pharmacy where I buy my meds. Ain't so. My credit card info was stolen 3 years ago when an online pharmacy I use was hacked. Apparently, they keep selling the numbers, so the calls will start up after a couple months respite, but originate from a different number to defeat call blocking.
Call my mobile repeatedly, every other day. Finally spoke to them tonight. Female, hispanic accent, claiming to represent - yes you guessed it - a Canadian pharmacy. Of course, I have no business with any Canadian pharmacies and I asked them to take me off their calling list. The woman responded, someaht flippantly, "OK, Bye!" and hung-up.
