Why has my monthly direct debit increased?
Since first joining Bulb months ago my direct debit was agreed at £81.69 and that's whats been taken on direct debit but I've just noticed this morning that on my account the direct debit amount is now showing as £96. Surely you can't just increase my direct debit payment without informing me first. What's more annoying is that I'm over £200 in credit anyway. I need an explanation.
