But as posted by others BT is doing nothing wrong OFCOM will take no action speed estimates are just that estimates not speeds set in stone your line cannot support faster speeds and that is all that can be said

Still doesn't say they deal with individual complaints. ie. they will investigate your complaint on an individual basis and get back to you with the result.
They only take action if the receive hundreds or thousands of complaints about exactly the same things and even then the quote says "your complaints can lead to us launching investigations and ultimately to us taking action" not that it will take action and that is assuming the complaint is upheld, which I doubt it would be in this case.
Anyway this is now going round in circles and is going off topic.
