i got a new phone and plan on the 10th of march. i've been getting a lot of calls from collection agencies looking for the previous owner of this number. i've told them they have the wrong number several times but they keep calling back. do you think verizon would change my number for free if i stopped in? i read somewhere there was a 15 dollar fee for changing numbers but it isn't my fault they gave me a number with such baggage attached to it. what do you think?
