For your information the BT and Microsoft phone call attempt scams are still being made and I have had reports from a number of NHW Coordinators.
They both come in the form of calls from supposed BT or Microsoft call centres usually stating that they will cut your internet connection unless you provide certain personal details.
Neither BT nor Microsoft would ever contact you in this way so please do not divulge any details or engage with the caller, simply terminate the call.
Even if you list the number used on call barring they often manage to get around this by changing their number on a regular basis.
Please be aware and stay vigilant.
