there is no cool off period - you need to cancel before service is provided.
if yyou would like some help/suggestions can you post the adsl stats from your router may need to 'show detail' to get all stats (if hub enter 192.168.1.254 in your browser and navigate to adsl or use a-z, if netgear enter 192.168.0.1) and run btspeedtester http://speedtester.bt.com and post the results.
are you connected to the NTE5 master or test socket or somewhere else? Do you have any phone extension sockets in your home?
Someone may then be able to offer help/assistance/suggestions to your problem
I had exactly the same problems as you and was informed i had a ten day cooling off period.
Cancelled on my eigth day.
interesting never seen that before - wonder if correct or someone gave you wrong information
Wrong info ? very probably as they told me id be up and running in less than 48 hours , then told it would be up to 15 days by another advisor.
Commision is king .
can you post the errors at the bottom of same page - may need to 'show detail'.
have you tried the test socket if you have an NTE5 master socket to eliminate any noise from your internal extension. ( I know that is the idea of the accelerator)
your hub has only be connected for 8hrs - was that the hub that reset or was it you who reset to try and improve the connection?
imjolly neither have I cancellation free before service activated certainly not after
maybe the mods can clarify - has there been a change in terms and conditions regarding cancellation and cooling off period
