Let's face it, it's not a charge a rich person will ever have to pay, it only affects people who have no money!
Yeah, because rich people have money in their account to pay bills.
Look, i do understand where you're coming from. i've been burnt in the past by transaction fees. I have a lot of debts, including a satisfied CCJ, so I m am not going to be on a high horse or anything. It was only after I found out I was pregnant that I actually started being good with money!
But the only person I blame is myself. It sounds like you knew there wasn't enough money to cover the bills, but you didn't do anything about it. Now, you can try talking to Natwest and ask them if they can refund the transaction fee this one time, or you can suck it up and don't make the same mistake again.
I am not saying it's right for them to charge this, though, but it's just the way it is!
Also, I am a Natwest customer and when I have a negative balance with them, i get a text message saying to put money into the account by a certain time that day to avoid fees. If you don't have this, you should set it up.
