So this morning, we are being bombarded with calls telling us our internet is going down. The first was a 0808 number and we quickly added it to our blacklist. Just now, called again and this time from 0121 number? I logged into my BT account and it doesnt seem there are any problems in my area?
Report the numbers on BT Report a Scam Call. It will help BT to observe a pattern of these calls, for their blacklists.
Had similar situation last week, and asked neighbours, who also had calls.
This suggests that your area may be being targeted.
