I've been getting this call all day long, same thing: Matt P. I hit call-back just out of curiosity and had to quick end the call because the call-back added a country code before the 516 and underneath it said "Peru". The last time I got this call was just a few minutes ago and, instead of hitting call-back, I used a landline and put in the two different numbers with this "Matt P" notation, first the 516 number and then the other number "646-779-6665. But resulted in a recording saying "No one from 'the association' is available to take your call". It's so annoying to get these constant calls. Mine's a new phone and I'm having trouble getting used to it as it is.
While I don't "answer" calls that i don't recognize, I DO want to know who's calling me because if it's someone unwanted, I want to nip it in the bud. I usually let them call then call the number back later to see what I get, as I did in this case.
