I have had a long running saga with BT and our Business Broadband line - moved house in February to a house with a BT provided line, only about 1.2 km from the previous house, numbers on the same cluster at the exchange (which is almost exactly midway between the two houses) - sounds simple to transfer our existing (old house) number to the new one? Oh no - months of confusion, bills for £1,000+ for "cancelling our contract"- £150 engineer visits (including one bloke referring in racist terms to the call centre people in India - "They don't what the fuck they're doing") and more - as well as loads of lne drops and simply not bloody working. We have the "always on" dongle on the router that should flick across to a 4G connection rather than the wire if that drops - dongle doesn't work.
As at today we have the new number, it works most of the time - but the line/wifi drops 3 or 4 times a day. For the moment, as it's not mission critical, we've just given up hope and can live with the line drops.
The best bit is that an email arrived to today saying "your compaint is resolved" .... and if we have a problem inviting us to call 800800154 - now, spot the error in the number? That absolutely takes the biscuit.
As you may imagine there is a parallel activity relating to the billing . . . .
