Search Results: find a phone number for free

I'm using a free text and call app that gives you a random phone number so you can call someone and it lets you change the number anytime (I didn't want to use my real number). So I was using the phone number the app gave me to call my ex-boyfriends dad. (My ex boyfriend who broke up with me less than 2 months ago because his family was moving to another county) wanted to stay friends with me so I was fine with it. He doesn't have a cell phone but I have his dad's phone number... It was the only way I could get a hold of him because he doesn't have a phone and his birthday is coming in 2 weeks and I want to tell my ex "happy birthday". So I was thinking of having to call his dad's number so I could talk to my ex, but I don't know if his dad will let me talk to him or he might report me for "harassment". His father is a psychotic man and is very strict. I'm just scared if I call his dad and finds out its me he might think that I'm stalking my ex, but in fact I just wanted to say "happy birthday". I'm nervous if he's gunna report me to the police for "harassment", there's just no other way I could talk to my ex who's now my friend (and he was okay if I wanted to stay friends with him) What do you think I should do? I mean I'm being nice here to him, just want to let him know that I am his friend and want to talk to him on his birthday, (this doesn't mean I want to get back with him because I don't), but I'm nervous what his dad will say if he answers my phone call.
