I was going to go into a detailed story about each time I've been shafted by a bank.
Instead I shall sum them up in a simple easy to follow process.

1)Find problem
2)Contact bank
3)Wait in queue (standing in line or with phone wedged betwixt ear and shoulder)
4)Explain problem
5)Ask for clarification
6)Listen to complicated procedure or policy that has resulted in my problem
7)Puzzled, ask for further justification on said procedure/policy
8)Ask for alternatives
Then either
A) Find none, become incredibly frustrated by the whole business and (optionally) cry
B) Get a half baked solution and feel exhausted.

Example 1
I get a cash card to take to Australia from a bank that offers it as a commission free way of taking money out abroad. It doesn't work. I have to borrow £1000 from my cousin as I'm in a foreign country with no money. I get back and they try to charge me to transfer the money over to her account. I show them all the receipts of all the atms I used to try and get money out. They ask me if I know my PIN - I show them at the cash point outside that I do. They agree to transfer my money for free. I feel exhausted.

Example 2
The same cash card. I can still only use it at the atm but I'm in England so it works. I ask to get it upgraded into a debit card so I can use it in shops if my proper card is out of action for any reason. They say no - I don't have a good enough CREDIT RATING. For a DEBIT card. I get frustrated and cry.

Question for the audience
I recently got a letter from my online savings company suggesting I set up a regular saver. I used to use this account all the time and got a great rate. When I stopped getting the rate I trasferred all but £300 out and now my interest has dropped from 15p to 10p a month. How can I get across my frustration without just writing a letter that just gets filed under "Thank you for your comments"?

Do you mean
You're getting (3.33*(10^-4)) interest? Because fuck me, that's shit.

Exactly
And I've just seen the following on their home page for the same bank account. "2.96% gross p.a. New customers only."

frustration
write it in human blood is a good suggestion... or wrap the letter round a brick... a combination of both may work.
