Referrals paid by Cheque - Why?

[#1]

I have just received a cheque for £5 being my referrals payment due. Why is this not being credited to my Direct Debit Account as registered on the Referrals account?

Please see this thread.

Thanks Matt. I have DD details on record so hopefully it will be paid by BACS next time.
