“If you find that you have less money available to you than you expected over the weekend, it may be because we reduce your balance by any amounts that are due to leave your account on a Monday… This should not be happening as the money remains yours until the payment is due, and we are working on changes to stop this from happening in the future.”
You can have access to these funds over the weekend if you call us on 0800 151 0404 or visit a branch"
