@chrysalis that's interesting and maybe worth another shot. Although I expect its like working back to zero with the call outs.
Hopefully Zen have detailed notes of previous faults on BTW to hand to TTB.
(@Alex Atkin UK, that's British Telecom Wholesale and Talk Talk Business
)
To TTB it will look like a new fault, but if Zen report it early enough, it becomes an Early Life Fault on Talk Talk's systems.
This should give it a higher priority with TTB and more weight on their systems to be fixed.
