I gave you mobile number a quick call, I'm sorry I didn't get speaking to you today. I've ran a few checks on your connection and I can see that an engineer has been booked for the 23rd. I've taken over ownership of your case and I'll follow up with you again on Saturday to see how the connection is performing following the visit.
According to the mod who has taken ownership of your complaint there is an engineer booked for the 23rd.
If you do not wish for one of the mod team to have ownership and deal directly with you then it may be an idea to say so.
I fully realise the frustration you may be suffering from but the mod team are best placed to get you sorted.
Cancellation of your service will be subject to the following conditions:
You will be able to cease without penalty if BT is still unable to improve the speed measured by the BT Wholesale speedtest above your Minimum Guaranteed Access Line Speed.
The Minimum Guaranteed Speed relates to line speed only, not to download speeds.
BT are incorrect about only the first 90 days, if it develops a fault that cannot be resolved after following the other steps of course you can cancel without penalty as BT are in breach of contract.
