I have been receiving calls at random times through out the months from all sorts of different area codes and numbers, Usually I avoid unknown numbers because of the obvious reasons, scams! But every once in a while I ansewer.
The first person asks me verify my name, I do and they say please hold. I am then transfered to (typically) a hastly and aggresive toned person who asks me to verfiy my address. I do not, simply because they will not tell me what this in regards to, not even the usual "this is an attempt to collect a debt" which I thought they had to state.
After a brief back and fourth, and me deciding not to give them anything until they give me some sort of understand about the matter they just hang up. I am then sitting there scratching my head about the whole interaction.
