UPDATE --
Well. Resolution has been achieved.

I left another message (3 total) with Supervisor this morning and was all prepared to escalate it by calling my bank branch manager if I didn't hear back today.
Supervisor called me back with apologies saying that he was out of the office and "How can I help you?"
I told him that I had a question concerning one of my accounts that had to deal with taxes. I explained the conversation I had with SB by saying "There seemed to be some sort of communication breakdown because I simply did not understand how the answers he gave me pertained to my question. Maybe I asked the question incorrectly, and there was frustration on both sides but I feel that his final comment to me "You have to do this, Lady!" was completely uncalled for."
Supervisor audibly sighed. "Mrs. JPcher, I sincerely apologize for your experience. Let me try to help you. What was your question?"
I gave him my question and he answered quickly. A little difficult to understand, so I asked a couple of follow-up questions which he answered. He ended by saying that I should feel free to call back if I had additional questions.
I asked him "Is it okay if I call you? I'm sorry, but I do not want to talk to SB again. I really don't think that he and I are a good fit."
He said "Oh, don't worry about talking to SB again." Then he gave me contact info for a person that will be taking over my accounts. "If you find that newSB is not a good fit for you, please feel free to contact me."
Now,
that is what I call great customer service.

Thank you all for your responses to this matter. I appreciate the encouragement to talk to his supervisor instead of just letting this drop.
