Since you rely on someone who is hearing - unfortunately no one is hearing in my house, apart from little kids.
I have decided to use BT's own online troubleshooter and submitted it.
Post back after you get connection fixed. Even young children could tell if the line is silent or if there is any noise apart from the announcement - crackle, hiss etc
Happy to report that the line has been fixed a few days ago and the speed returned to where it was. Got around 3.25 Mbps on speed test which is normal.
Could I request ADSL 2 for both lines and see how it goes?
great line fixed and speed back to what it was
I have asked mods to see if they can help get both lines upgraded to adsl2 mods will post here
Thanks for posting back.
I'm pleased to see that the fault has been repaired. We can help with the change to ADSL2 from here. We are extremely busy at the moment and it will take us some time to get round to picking up your case. We'll get to you as soon as we possibly can.
I have sent you a private message with instructions on how you can send us over your details and we'll look into this for you. See: Private messages
