Bests & Worsts Reviews from Amazon

Worst credit card ever. I did not listen to other reviews and now I'm obligated to cancel this credit card in less than two months that I opened it. Long story short, maxed my credit limit buying holiday stuffs. Paid it off within two days. Now card is declined for more than a week for any transaction even though there is no balance . Reasoning is that I made a big payment of 2500$ and apparently that's too much money to handle for them and they say that it will take another full week to process the payment because it was a "big payment". Dude, I pay that every day on office supplies. Perhaps I should open a credit card company myself since apparently I make more money than they do.
