Sigh, so that's exactly the conversation I didn't want to have. Speaking to a mate who works in another part of the country, he's suggested that I wait a week and then try and get a Boost engineer out to take a look.
Ultimately they're all going to come to the same conclusion that the cable is dug in, not ducted and thusly needs the path digging up to resolve. Which they won't do because the numbers don't add up sufficiently to warrant the work. Nuts.
Cheers for the pointers, I'm going to have a read and see what I can find.
Edit - just found my original order email:
Nope.
A boost engineer their is no such thing and thats the type of stuff that made me leave. Randal i think im going to upset you now!? You need to go on BT Wholesales website to see if they have changed your speed estimate from the year before thats what they have been doing, lowering estimates so no intervention is needed if your speed is in line with your new estimate.
PS not all estimates have been change. IMO i think they have lowered it to stop customers complaining about speed because the cables are not upto the job as they have limited twists are bundled together in some places joined without shielding ect. And even though you had an estimate of 57.7 if they have changed it they will be working on the new estimate if they have changed yours. Just argue the fact at point of sale it was 57.7 and that forms part of your contract the new speed estimate is not part of your contract as the speed above was expressed as what you would get. Tell them you expect to be notified with any reduction or change in service as they agreed in contract to provide the service stated.
You may have to go through with any threat to cancel. I did last year i said i would rather go back to ADSL as it was cheaper and i didn't care. So they asked me how much is the ADSL i told them it was £15 then they said i could have my infinity 2 package for £17.50 and they would put me on a 12 month contract, so i took the deal but this year i had enough and left. You have got a fight on your hands. Good Luck
