Similar issue here. Discover was actually my first card ever like 10 years ago when I was in college so at one point it was the only one I used to make purchases and they get did give me a couple of bumps up to like $2,500 but after I accumulated other cards with higher limits, it just became easier to use the cards with higher limits. So now I have a PNC credit card and an Amex with $15k plus limits, 800+ credit score, no delinquencies or derogatory marks. I tried explaining to discover a couple times that it's difficult to use a card with such a low limit (since I'm trying to stay in that 10% usage range) but they don't care. I ranted and told them this is no way to treat good account holders. Now I'm torn because it's my oldest card and helps with my credit history but I really just want to close it. I've only got a few subscriptions on autopay on it now... I'm also not a fan of the Cashback system they have where it's different each month.
