Interest Free Credit Card Visa

Payment Credit cards! negative mark on your credit report if the lack of use?
Recently I paid all my credit cards. Now I am debt free! Either way, I read articles in the past where the credit-card companies can close your account if you do not use your account everything. I've also read that if you close a card off (after you pay of course), then this can be a success in your credit score. I'm confused! I have a Walmart card (not discover card) and card (non visa) … I really do not want them as interest rates are 22% or higher. I will not use more, so if you close them so bad?
