I have had the following message showing on my accounts for many weeks now:
Hold on tight. Your speed boost is on the way…
Your speed upgrade will be ready to take your connection from up to 20Mbps to up to 70Mbps. It's all thanks to DOCSIS® - the magic in our cables. Look out for it between December 2016 and December 2016
It is now January 15th and still no sign, speed still at 20mbps.
