In the evening, I got a call from 0480 896 749. No one bothered to leave a message. A short time later I one from this number, with only the last two digits different. Utter pests. This time I kept the line open for at least an hour in the hope that they wouldn't be able to use this number to harass anyone else, but that may not work these days.

Received two missed calls from same prefix (0480 896 xxx) within an hour of each other. This one and other ending 748. Gotta be a nuisance call. Dogs.

I don't tend to answer phone calls that come from a phone number I don't recognise.
