Sorry to hear your connection is dropping.

Our tests are showing a external fault so we'll get that raised for you.

Apologies for any inconvenience caused.

[#4]

Thanks.  Is there a way of being updated as to what will happen next?

[#5]

At the moment, we've no updates I'm afraid. The fault report has been accepted by Openreach as of this morning. We'd usually receive updates within 72 hours. Our faults team will keep you updated via this ticket

Has there  been any update from open reach?  It has been over 72 hours.

[#7]

I can see one of my colleagues in the faults team provided an update around 1 hour ago.
