Reward Points

I have alot of credit cards which I thought would give me alot of rewards points, but unfortunately not all of them works really good, I believe there are lot of scam and spam on this cards so I ended up closing this accounts of mine, I thought they sucked my money, but somehow some of this rewards point works somehow, just like my Wells Fargo rewards card, yeah they put a rewards on my account but the sad part is that their rates on their credit cards are way too high than other banks or credit cards that I have, ggrrrr.
