Thanks for the update. I've re-checked the connection stats again now and the connection still looks stable since 06/10. Just to confirm, is the telephone number in your community profile correct? Please do not post any personal information on the Community.
I've had a good look at the line from here and ran a few further tests.
I'm showing the AC balance on your line is very low.
This will need a line engineer arranging.
I'll drop you a PM with the info required.
