<prompt> Human: So I had a CC thru Bank of America back when I used to use them for checking Ive long since moved to a CU. I paid them off, and have had a zero balance with them for quite some time now. They sent me a letter stating that they will be closing the account due to lack of activity. I know that closing accounts hurts your credit score, and that they take the length of time an account has been open into consideration credit age when calculating the score.My question: should I keep the account open? How bad could it hurt my score if they close it?  <response>: Go buy a pack of gum, then pay it off...
