Barclays - and why I left...
7th June: "Dear sir, your account is 10p overdrawn. We are charging you £10 for this letter."
14th June: "Dear sir, your account is £10.10 overdrawn. We are charging you £10 for this letter."
21st June: "Dear sir, your account is £20.10 overdrawn. We are charging you £10 for this letter."
28th June: "Dear sir, your account is £30.10 overdrawn. We are charging you £10 for this letter."
3rd July: "Dear sir, we have bounced (a standing order) due to insufficient funds. We are charging you £25 for this letter."
4th July: Me: "I'd like to close my account, please."
(True story - I had just started work and joined because they had a branch onsite where I worked - yeah, it was a long time ago!. Anyhow, I asked how they justified £10 for a letter, and why they felt the need to send another letter every week, and the answer was that they had incurred extra expense by sending me each letter. I tried pointing out that I was losing a morning's pay to see them in person, their letters - in fact the whole process - were automated and hadn't required ANY human intervention and certainly not £10-worth of computing power, electricity, ink, paper and postage, and while I could understand one letter the rest were not jut overkill but an insult. Especially since my "unauthorised overdraft" was incurring something like 30%/month 'fees' and the interest would be added when (ha!) I cleared my unauthorised overdraft!... and yes, those fees would be levied on the letters too. I also pointed out that one of my workmates had gone considerably more overdrawn than I had but not received any letters. I'm sure the fact that his parents had their mortgage through Barclays didn't affect the branch's behaviour in any way...)
