If uve got an iPhone n jailbreak it u can get an app that will allow up to block any phone number you want or try ringin your service provider and ask them to block the number for you. If that's any help to you but I get calls of these types of people all the time and I'm getting annoyed so I got the app and started blocking these numbers

I have had 2 calls today from this number, and I like some other people, don't answer unfamiliar numbers . But thanks to everyone for their information :)

Just answered a call from this number following a missed call from it yesterday.  I was told they were calling from Vodaphone and they then tried to sell me a Smart phone.  Said they could match any price etc etc.  call lasted about 2 mins and the woman on the other end spoke in an Irish accent (not sure that makes a difference).

Will not be answering again in the future

I've just received this telephone number,but I don't know who that is .Since I am used to ignoring unfamiliar telephone so I didn't answer it.But I wonder if it is an important telephone.
