From my experience as an ex-BT Engineer Hoppy, its my firm belief that the fault lay in the Exchange and that whoever was going to come along this morning, had a quick look at this yesterday and found the problem then.
Although that doesn't explain why nobody has contacted me this morning to report that a visit will now not be needed, thus saving me have to wait in since 08:00 today !
But it all helps to build up my case for some compensation here. I have spent £25 on my dongle since the Broadband went off on Sunday.
