<prompt> Human: I recently applied for a credit card through my longtime banks website. I got a good offer, and got interrupted before I could click accept. The website timed out, and upon logging back in, I couldnt find any indication in my account that Id been given an offer. Wanting to continue to study the offer, my dumbass resubmitted another inquiry, and this time, it told me to await more information in the mail. Fast forward to now, I have been sent two credit cards, but I only need one. Ive yet to activate either, but wanted to know more about if I were to close the second one.I called customer service, who said they could not discuss specific credit info, and Id need to inquire with the credit bureau. Surely, its not uncommon for people to open credit cards and decide not to accept the offer, right? Couldnt I just close it? So I called a banker just more customer service to generally ask the best way to handle it, and the gist is that closing a credit line is bad, mmkay? Totally frustrating that they can issue 11,000 in credit, but dont have answers on how close it!I only needwant one credit card, but Im feeling like at this point, the best thing for my credit is to activate both cards and just let one exist. As I mentioned, the two cards total total 11,000, which add to the card Id already been using using for years, at a much more modest limit of 500. Any advice is much appreciated. Edit: formatting  <response>: Keeping both open would be better for you long-term
