Hi Ash
Sorry to hear you are getting scam/cold calls to your number. I would recommend emailing our BT Security team on abuse@bt.com, and they may be able to look into tihs further. If you are getting abusive calls etc it may also be worth contacting your local authorities.
Please note - I have editted the title of your post so as to avoid any personal details, such as a landline number, being given out.
Kind Regards
Ryan
