Very odd. A man speaking in Spanish asked for "Pedro", when told it is a wrong number, they ask for my name. I replied "who do you want to talk to?" and they asked again for my name. I just hanged up. This call was from (407) 477 4138
Later I received the same call from a woman -also speaking spanish- using a different number ( 323 215 1249) with exactly the same strategy: asking for Pedro then asking my name when I told them they have the wrong number.
I received several phone calls from a woman always speaking in Spanish. She always asks who is she speaking to and never states her name and where is she calling from.
