What should my bank do for me? Have you been in this position?

I had a save money credit card from my bank & i applied for a another card which was the cash back credit card & the lady thought that i wanted my save money which is my old/first card cancelled but I didn’t I wanted both cards , so my credit score probably dropped a bit. All the lady did was apologize & for miscommunication so I need to call her back when I have time to figure out what they will do for me since they can’t uncancel my old card & since I was but busy at the time when she called.
