Being a muslim you should not do business with them as they are charging interest. Now let me guess, you applied card on your own, you are using on your own free will and now complaining that they are charging fees. Why not cancel them and get rid of this problem once and for all. But, wait you can't do that or else how can you purchase things that are latest and trendy, right? Buddy, stop blaming others and start being responsible. Why not bring a good name to much maligned Islam by starting a campain against using credit cards? Why not teach fiscal responsibility to fellow Ummah brothers, why not learn the good values that Islam teaches about living a life of simplicity without complications?
