<prompt> Human: Hi,So I went to my bank recently, Chase to get a new debit card made. While I was there I was told all sorts of offers and stuff per usual. Then they told me how I could and should upgrade my Slate card to the new Freedom card. I asked them Im good for that as long as its an upgrade. They said sure it is. I said ok, signed a document and left.Well, its not an upgrade, its a new line of credit. Which angers me. As I do have a balance on my Slate and now I have a new card that I will likely not touch unless I kill the Slate card after paying it off.I know cancelling cards does more harm than good, right now I have 3 credit cards.So what Im asking is, should I bite the bullet and kill this freedom card? Should I pay off the Slate card then kill that one and keep the freedom card? Or should is there a way to get my slate account transferred to the freedom? Or is it too late on that?Thanks for any advice for helping a stupid person make a mistake with little thought in the process.  <response>: Well now you have a bigger credit line, so every dollar you spend equals less credit utilized. So you have a better credit utilization ratio. And if you just use all three cards sparingly, youll have a better record of on-time payment history.So really, this is a good thing.The only potential negative here is your average age of credit history will drop since this is a new card. But unless youre using your credit to make a large purchase in the near future, this isnt all that bad, and is certainly outweighed by the potential good.
