Just tried increasing my overdraft to avoid trouble ahead, I have a Direct Debit coming out tomorrow and not enough in there.
I misunderstood and increased it to £300 rather than by £300. It has changed my overdraft to -£300 , not the £2300 I needed to change to. I am now £1900 over my overdraft limit

There is no helpline open until the morning, will they understand do you think if I explain ? I'm worried sick now, can't sleep.
