"Thanks for your patience. I apologise for any inconvenience that this fault has caused you. I have re-tested your connection finding no problems. Your connection has been remaining stable since Interleaving was applied. This process will increase ping times but not to the extent you are seeing"
So interleaving must still be applied to line, or are everyones wires crossed?
Can interleaving please be removed from the line, thanks

Hi MrN,
I've had a senior faults agent look into this for you and they have found a reporting issue deep within BT's systems which shows that Interleaving is still enabled on your line. I have placed a manual order to remove it totally from your line. The order ref given by our suppliers is 1-10894713955 and its due to complete by 20/2/12.
