0843 87 nusience calls

How do I stop getting phone calls from this number. It rings once then hangs up every day and changes the rest of its number every day so I have been blocking a different number everyday.

@Another Not much you can do except keep blocking the numbers. It happens on all networks.

Edit: You can also register your number with TPS: https://www.tpsonline.org.uk/

Unless you don't mind having your number changed? If that's not a problem, give o2 a call on 202 from your mobile and ask them to give you anumber change - the first one is free. I would also recommend that you report these nuisance calls to them as well.
