Time to ditch BT?

I ditched BT as an ISP over a year ago, in protest over their plans to implement the vile Phorm DPI system.  This proved easy to do (apart from the 4 hour New Delhi runaround trying to get them to stop charging my credit card), and resulted in a threefold increase in my download speed through the new ISP.

However, our landline has remained with BT.  But I'm getting fed up with what amounts to an added 10% surcharge for not going with Direct Debit (it's a fixed fee of £4.50).  The search is now on for a land line service that isn't run by such an avaricious bunch of money grabbing crooks.  Or I just cave in and pay by Direct Debit.
