Vodafone Broadband Renewal 900mb

What is the best renewal tactic for Vodafone?

I signed up for their 900mb broadand for £26 pcm ( discounted by 50%) - now the 2 years is up what is the best renewal tactic?

The price went up to £29 last year. I am also a Vodafone mobile customer but that discount was cancelled out by the price rise.

Now they are offering me £29 pcm plus annual price rise for 2 years- is that the best going?
