I've built up a crazy amount of credit, but was refused a refund in store. So, I switched my billing preference from auto top-up by Direct Debit to the 'pay with credit' option, even though it's going to take literally years to use up.
However, the DDs are still going through. I've searched all the account options in case there's something else I'm supposed to have done, but I can't find anything.
I understand these things don't always happen overnight, but it's been three months now! Meanwhile, my credit is like the never-emptying porridge pot.
