I'm area 25 South Wales and I'm exactly in the same boat as you , I spoke to someone on weekend and they were texting me with a date when the cables are being upgraded in my area , guess what no text yet
Seems to be working as normal at the moment afternoon 25 aug ( 25ms ping 104Mbps download speed) . Speedtest and other connection testing site still think I'm in Glasgow but other than that everything close to normal
Thank you for keeping in touch, I am sorry to see you have continued to have trouble with your connection.
I have taken a look and I think it may have been related to fault ref F005559612 there was a power surge caused by a local business and it was tripping the switch in the exchange. This has now been resolved and the connection looks to be ok from here.
How have things been looking for you since then?
If you are still having trouble let us know and we will be happy to take another look.
