I am so mad at my bank. they somehow thought to charge me for a credit card i didn't want.
gpt
That is not good. Did they give you back your money? 
human
Yes but i had to spend a whole hour on the phone explaining why they were at fault.
gpt
I would be upset too, they need to do their work properly.
human
I agree!
gpt
I am glad that you got it cleared up.
human
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.
