Hold on tight. Your speed boost is on the way…
Your speed upgrade will be ready to take your connection from up to 50Mbps to up to 70Mbps. It's all thanks to DOCSIS® - the magic in our cables. Look out for it between January 2017 and January 2017

Mine got pushed back yesterday from Feb' to May-July. Another case of VM's wonderful efficiency.
If you look at the image I posted you will notice mine has been 'pulled back' to 2015 not pushed forward
