I worry about Nationwide. I thought they would be good people to have an account with and popped in to open one. Oh dear, times have changed since I've been away. You can't 'pop in' anymore, you have to have an appointment with someone with a fancy title. In an empty branch, you can't see this person - you haven't got an appointment (even though they are sitting there). So, I made an appointment - earliest being 8 days later.
The day before the appointment I got a message saying that due to staff illness, my appointment would have to be cancelled. Could I phone to make a new one. I did that and my new appointment was now 14 days after I first popped in to open an account. At that appointment I was told that I needed to bring a domestic bill with my name on it before they could open an account. I had my passport, driving licence but this was the first time they thought to inform me that a domestic bill with my name on it was something to bring with me to my long standing appointment.
So, another appointment was necessary which was made - for 19 days after I first popped in to open an account. As if things couldn't possibly deteriorate any further, the branch manager called me to say that due to staff illness, my appointment would have to be cancelled. I gave him a brief summary of my month to date with Nationwide and asked him if, genuinely, there was only one person in the entire branch who could physically open a new account. I asked that as branch manager, is it not possible that he could carry out such a task. I asked him whether, in these times of hardship for banks, whether he thought Nationwide's efforts to grab me as a customer were quite good enough in his view. I received many "I can appreciate your frustration" and "I can only apologise" responses, but no, nobody else apart from Miss Sicknote could do this highly specialised banking operation.
Nationwide - to me they create as many hoops as they can for you to jump through, then hide the hoops.

I managed to live without them, as I have done all my life.
