Energy Switch Problems

ARCADIAN

At the end of July I signed up with Energyhelpline to switch to British Gas for a duel-fuel fixed rate deal, paying quarterly when billed. Seemed pretty good as I would also get £15 cashback, or so I thought.
A few weeks later I get a welcome letter from British Gas but stating that I had agreed to quarterly billing on gas and monthly direct debit on electricity.
I e-mailed British Gas to explain a mistake had been made but they insisted that I had signed up to a direct debit on electricity.
I then got back to Energyhelpline who informed me that British gas must have cancelled my contract with them,and set it up direct.They also informed me that because this had happened I would not get my £15 cashback.
How can any of this be legal.
