I love my Chase Freedom World MasterCard. It was so easy to sign up and get started. They offer cash back rewards on every purchase. They also offer bonus rewards for different transactions each quarter. You have to sign up for the bonuses, but I have mine set up to send me a text message when it is time to sing up and all I have to do is text back. I haven't had to call customer service too many times, but every time I have, they have been very helpful and resolved my issue on the phone. I have had two instances of them flagging my account for fraudulent activity that turned out to be my activity. They called me right away and we cleared the problem immediately. I really enjoy the rewards from this card. My family and I were able to book a trip and paid for most of the airfare with the points we accumulated and we plan to do the same thing this summer. I would definitely recommend this card to anyone who wants a credit card with good rewards.
