im getting phonecalls from unknown numbers,when it first happened i answered the phonecall and said hello but there was no sound there at all, after that i got more phonecalls about 3 to 4 times a day (everyday) i just ignore them and hope they get bored but they keep doing it what should i do ???
Looks like some tele marketers have got your number. If you have to say "hello" more than once, it usually means that it is an automated computer generated call with an automated message.
Somewhere, I read that in such a case, rapidly hitting the # key on the phone keypad will make the computer "think" that something went wrong with the number, like inactive, and will program itself to stop calling that particular number.
I do this, but have no verification whether it works or not.
