So much for it being fixed

20mb line .. straight down to 3mb at 5.45pm. (1.7mb at 6.30)
Edit> Just called VM again & now they are saying everybody on the UBR is going to be affected by abysmal speeds as they can now see a serious problem.
All he could do he said was put it down as a complaint so a customer service person will investigate the problem and contact me within 5 days with any possible solution.
He gave a £37 discount this month & £18 discount next month & apoligised.
He also said to tell my neighbours(fellow vm customers) if possible about the current situation as they will obviously be entitled to the discount too.
So anybody on the cpc*-grim3-0-0-cust***.nott.cable.ntl.com ubr (DN35 7) area needs to call.
