Yeah I tought it had something to do with the work he was doing for my neighbour but it doesnt. And he knew my name and everything and yeah I could go on foever but it's really freaking me out please because he's knows where I live. Oh god oh god oh god
Someone reply please!!!

How did he ask for your number if you've never met before?
If you want a number blocked you'll have to call your phone carrier.

he rang my house phone, my neighbour must have given it to him
(stupid stupid neighbour, but not nearly as stupid as me)

do I ring costumer or account information??
this is not a drill. I repeat this is not a drill!!
please people I need answers precious precious answers
you dont know how much of a freak this person is

ok, well you cant really block numbers from mobile phones
the most you can do is ignore it, dont answer, and report it
if this person is asking you questions that make you uncomfortable then you can go to the police if you want to
otherwise yeah, call the customer service and ask them what else you could do about it, but they tend to not be very helpfull and just put you on hold the whole time

well if it's a mobile, then there's a porogram called 'black list' ( not sure of its name)
you add all the people you want to block to your black list and everytime they call they think you're phone is busy or not in survice...
and if it's a telephone, then you can only change your phone number I guess!

good luck

Lol add his/her number to 'don't pick up' or something, and when he/she calls, don't. Turn your phone on silent. If things get bad, tell your neighbour, tell the police, or even change your number. But it'd be dumb if you had to change your number + stuff. Just ignore that person. What did he/she do anyways? Ask personal questions? :S You could always make it clear that you don't want to mess around.

I dont have the black list thingy because my phone is reeeally old (like one of the first ever invented haha)
well im not changing my number because I only changed it a few months ago so I dont even have the money for that
well they rang the house phone at half 11 this morning(I usually get up at 2 on the weeknds because im a lazy biiiatch), and I didnt really know what they were on about because I was so tired but they said something about doing work for my neighbor and couldnt get through to her phone? so he asked for my mobile number. and I was like what the hell. but then he said that he was wasting loads of money ringing froma mobile to a housefone so I was like okaaay il send you a call me off it so..and then he texted me and I never texted back because thats when I was more awake and realised 'yeah this is pretty unusual'...so then he rang me and was saying all this crap like 'I'll be working for your neighbor next week do you want to come meet me?'
so then I was like 'yeah f*** off I dont even know you I have to go bye'
but yeaaah oh jesus

call the police girl. dont block him only. if he knows where you live he can simply come to your house.call the police.
