["I am so mad at my bank. they somehow thought to charge me for a credit card i didn't want.", 'That is not good. Did they give you back your money?', 'Yes but i had to spend a whole hour on the phone explaining why they were at fault.', 'I would be upset too, they need to do their work properly.', 'I agree!', 'I am glad that you got it cleared up.', "Thank you. I hope they won't do anything like that in the future."]
I hope so too, you should have reported it to a supervisor or manager.
My bank ended up charging me hundreds of dollars for something i didn't do.
