Users of credit cards know that the offers to get one never stop. Companies look for all the possible ways to attract more and more clients every day. They try to hang on people by proposing attractive plans of payment and special low introductory rates among others. If you are not careful in the way you use your card soon you will find yourself flooding with damaging, high credit card debts.
The acquisition of a credit card must be taken into consideration very carefully otherwise it will bring along numerous serious consequences. First of all, the company will initially approach you offering very good and low introductory rates. Once you choose them, they will increase them dramatically without notice, based on any reason (single late payment or a negative entry in you credit report). These are popularly known as "teaser" rates. Another common practice credit card companies have is to reduce the credit they initially granted you without previous notice, which can lead you into very uncomfortable situations. Consequently these unfair practices are driving interest rates through the roof.
People do not know that they have the right to fight and to claim the initial agreements that they signed up for in the contracts. If some of them change clients must be notified previously.
For more information on the topic, take into account that U.S. Senate Banking Committee oversight hearing on unfair credit practices gives documented recommendations. If you think that you have been a victim of any unfair practices by your credit card company; such as substantial rate increases, unfair penalties or broken promises; you can file for class action. You just need to contact more people that are in your same situation.
