Hi Dave,
Thank you for the details and clearing security.
There is an area outage at the moment, this has been going on since 01/09/19 and the fix date is showing 24/10/19, this doesn't necessarily effect everyone in the post code, all the issues you are reporting are pointing to this outage.
If you are still facing this issue after the fault has been fixed on 24/10/19 please let us know.
Kind regards
Paul.
