That looks like their settlement batches were no longer accepted. They deserve to lose their customers / go bust over that. Natwest will survive because not all their customers care about such stuff to the same extent, some may not even find out. Others are bound by their mortgages to have checking accounts with Natwest.

I didn't say that those things don't happen. I said that they are not acceptable. The fact that others fuck up does not give you an excuse to fuck up.

These are exactly the kind of discussions that I was hinting at above.
