Last year I had a problem phone kept buzzing noise . It took BT 2 days to find where the outside junction box was . I thought they would finish digging the street up . Answer I got was they had not updated there system for new boxes. I have been in same house for over 30 years never seen any new junction boxes going it . Seems they always have an answer of some sort they must think we are thick wells not quite lol .
No solution in sight to the email - it's a 'widespread problem'
Crackly line and broadband failing problem - it's not worth changing to Tesco or whoever - the copper wire will be the same and it will still crackle.
BT want me to try another new hub ... which they were going to charge me £39.95 for ... but I negotiated them down to ... £0.00 plus a discount on my package.
It won't fix anything - but at least I'll be £3.50 a month better off - nearly a pint of .... ☺
