I still haven't had notification of any price rises yet although i've been meaning to phone and cancel so it gets switched off after christmas.
Phoned just now and cancelled TV and phone line, downgraded BB to 50Mb and it gets switched off 1st January.
I was looking around at the weekend for other BB providers. Checked BT's site and entered my postcode, it said for a more accurate speed enter my house number. I thought here we go so did it.
Got cold-called by BT yesterday offering me infinity

It would be £26.50 for LL and Infinity 1 with a free install.
VM did what i was hoping they would and offered me the 50Mb BB for £19.50 even before i mentioned BT had phoned me. I'm happy with that, she also said if i wanted to move before the year was up i could cancel without penalty, i don't intend to though.
All in all a good phone call with a very pleasant lady who didn't try and convince me to stay with TV and LL.
Maybe they'll phone me later in the month, maybe they won't, not bothered either way TBH.
