Its not just area 21 same applies to area 22 and Bristol area. Seems to be virgin policy to sign up more and more customers knowing that the feeds do not have the bandwidth and just hoping old customer loyalty and inertia will keep them paying for 1/50 of their normal speed long enough for the new customer revenue to pay for extra bandwidth to be installed.
My apologies that you are having issues with your broadband connection.
I've taken a look at the high peak time traffic fault in your area which you mentioned and our engineers are still working on this to improve bandwidth. The reference number is F0034444101 and has a review date of 29th March.
I also noticed the downstream power levels are too high at + 16dBmV and as this will also cause an impact on your connection, I would like to arrange an engineer appointment to adjust these. I've sent you a PM (purple envelope icon, right corner) with some details for you to confirm please.
I recommend that you give them gyp over this 'review date'. Ask whether at that point they will have reviewed the remediation works so far conducted or will they review whether or not then is the time to start works.
The 'review date' is a meaningless term unless accompanied by the current actual planning status.
