<prompt> Human: Hi,I have three different cards at Chase bank and they all have different APRs. I just called to ask for them to lower my rate and was told what I currently had was the best rate available. When I told the agent that I had other cards with Chase with lower rates he said its all based on when I opened the cards. I retorted that Chase deemed me creditworthy enough for the lower rate so I dont get why you cant match it and he said that they will be reviewing my credit in January and if theres a better rate available Ill be notified. Should I have pushed harder? Asked for a supervisor? Something else?  <response>: I have no idea what the APR on any of my cards is. If you dont carry a balance, it could be 1000000 and it wouldnt matter at all. Are you currently in debt?
