See who's calling

For the last few days I have been getting calls from this number - the first time I answered and got a very unpleasant woman on the other end being quite rude because I refused to answer her questions. I now reject the calls but they still keep ringing.

They call several times a day letting it ring for 4-4 times then hang up, Its getting really annoying now, How can I block it

I have just had a call from this no when i answered my granchild was talking at the same time i asked her to repeat what she said and i got her screaming down the phone if i listened i would no what she is saying i keep trying to phone back to give her the same but no one is answering

Do not answer this caller.

Trying to sell etc
