I absolutely have been on phone calls like this.
The reason that to this day I will NEVER do business with Bank of America is that I was on a very similar phone call when I tried to cancel a credit card.
By the end of the call I was saying, "It's not you, it's me. I just don't want a credit card right now." It was like breaking up with an abusive, co-dependent boyfriend who could not get the word No.
The last time I had to deal with BOA is when I worked for a company that banked with them. I can't remember the details of why I needed my money ASAP at that time in my life, but the only way to cash this check drawn on their bank in a timely fashion was to go to the branch near my work. I had two options - pay an extra fee for them to cash their own check or get an account with BOA. Every week they'd give me their pitch and every week I'd fork over the extra money to cash the check. I'd explain each time that it was worth it to me to not have an account with them. So every time I cashed a check I was explaining to their tellers what pieces of shit their employer was. Though I am sure they knew that already.
