Prank calls

it had lasted for a few days...
my phone was ringing without ceasing...
the moment i picked up the phone...
the person hanged up...
and for several times...
oh shit...i cant concentrate on my reading...
trying extreme hard to ignore it...
needed to unplug the connection wire in the midnight...
in order to avoid those annoying rings...
"Ring ring...." i hate that!!
please stop calling...
i tried to look for help from the reception today...
not very effective really...
the only advise i get is to divert my calls to voicemails...
umm...ok...fine...but that doesnt mean he would not call again...
have to let my phone "rest in peace" for a period of time...
hope that whoever the person is...
would give up and stop his nonsense...
