Hi, This number has been ringing me all week, at least 5 times a day, if I let the machine pick up, no message ir i answer they hang up.
Anybody know who this could be?

thanks

No idea, but contact BT and ask for their malicious/nuisance calls service.

They will provide you with their "Choose to refuse" service free for 1 month preventing that number from calling you. Within a month, the caller should get the message.

"Choose to Refuse" is available free for one month but is chargeable thereafter. The service can be cancelled at any time.

For more information and to request the service, call BT on Freefone 0800 169 2707

Thanks have done this now.
