Phones and hangs up without saying anything.

Been ringing evenings and middle of day. Not a number I know, so I don't answer.

hung up without answering

I have been getting many calls like these at night and on weekends on my landline. If I don't know the number I just don't answer. I have trained the kids not to answer numbers like these. If someone I know wants me they ring my mobile anyway! I never buy over the phone anyway.

Calls during the evening. Doesn't say anything and then hangs up.

Phones, background noise like a call centre then hangs up without saying anything.

This number was the first of 10 calls (averaged about 2 per hour so far) today. All others were different numbers with 02 area codes. Did not answer any - left them to my Call Guardian to deal with. So many calls suggests someone is phishing so would avoid like the plague!

Nuisance caller. Calls and says nothing.
