Upgrading to plusnet fibre offers/deals ?

[#1]

My exchange has finally been upgraded to fibre broadband and saw that plusnet have various offers but disappointingly these seem to be only for new customers and I am only offered a £22.50 a month rate online for upto 38mb despite bt suggesting that average speed would be between 38-56mb.
Does anyone know of any deals as I can get cheaper with plusnet as otherwise might have to go with cheaper Bt with free BT sport (without the need of a sky dish) otherwise
Thanks

If you give the Customer Options Team a call on 0800 013 2632 or 0330 123 9197
    8am - 8pm Monday to Friday
    9am - 7pm Saturday or
    9am - 6pm Sunday
and explain you want to upgrade to fibre they are quite likely to make an offer which from my experience is at least as good over the length of the contract as new customer offers.
In view of the range quoted in your estimate trying a 76/20Mbps product for starters would be worthwhile, but again discuss this with the COT agent.
