I don't know who keeps ringing me on this number, I don't know the number and I don't answer any numbers that I don't know. I've blocked this number because I just want to be left alone. There is another mobile number that I don't know who keeps calling me 0488 805 557, which I accidentally unblocked and now I can't reblock it. I was wondering if you might know how I can block this number this number again please?
