OMG! I discovered a way to get them to stop calling and to tell if it is someone legit or not without having to talk to them or ask them questions or discussing anything with them. They simply say, "Thank you for your time..." or just hang up and leave you alone. This may not work for everyone (specially if your name is Nathan Smith or something) but it works for me. This number called me along with a few other numbers all who had someone speaking in a Pakistani accent and ask for ***** Perez.... To which I replied, "No hablo Ingles..." and they always leave you alone. Some ask if there is someone that speaks English and I say "Que? No comprendo" and they say bye. The thing is that they are BSing us, lets BS them... How are they going to prove that you really don't speak English?? If they are legit, they are bound to have one person somewhere (anywhere) in there company that can speak Spanish but if they are in Pakistan or India or China then they can't disprove that you can only speak Spanish. One time they starting talking crap in their language and I spoke in a few sentences in the Queen's English before I articulated my discontent with their existence using ill profanity and slanderous remarks. They left me alone too... (I don't recommend the latter BTW)
