Taking forever to exchange dollars

I requested from your FB page which documents I would need to take with me in order to return unused US dollars. I was told, ID, latest proof of residence, and proof that I had been out of the country. As I rent, I took along my latest rental invoice, only to be told that I could not be helped without a lease agreement. I returned to the FB post and told who had given me the info! that they had ****. Received a call from a DARWIN? two was more concerned about who I thought had ****, rather than assist me to sort out the problem, which was to exchange the dollars. I put the phone down on him. His attitude was that of, oh so we should not assume that you rent? I must just say that I also had my passport, which clearly shows exit and entry customs stamps, I even took along my cruise embarkation ticket, but no, all she wanted was rental lease as rental invoice was not acceptable. I was gobsmacked with its DARWIN ? as well as the consultant's attitude. My lease agreement is dated 2014' I'm sure I will now be told it's outdated. I guess I am truly wasting my time with standard bank?
