Was my friend anonymously harassing me?

A while ago I had this person calling themselves anonymous harassing me by text, their number was displayed though so I asked a friend of mine whose number it was and the told me it was this boy in my class. There's been this female friend of mine that's been avoiding giving me her number and when I finally got it, it matches EXACTLY to the apparent boy's number. However, this girl said she did get her number changed a while ago. Could it have been her harassing me and not the boy? If the boy did get rid of his number, is it even possible for the network to give the same number to someone else in this same class? I mean there's so many people on the network, what are the odds... Was it her harassing me because I don't want to randomly accuse her of something, what do you think?
