the idea of using the debit card to manage your finances is a great idea, i totally agree cos i was and still am the victim of using the credit card like no tomorrow. but if u have good self control, a credit card is also a good thing for saving times and effort in managing your finances.
For example, u can have all your bills on autodebit via your credit card since some of the billing dates are not the same and our salary is only at the end of the month of beginning of the month. By using the autodebit u wont miss the payment dates, just have to pay off the credit card once a month. And also when there is an offer to pay for something for interest free installments, which i think it is good to use for the right thing, for example like paying for medical bills in an emergency case or pay for paying for one year lesson or membership in advance with a credit card that offer u to pay in 12 months. That way it will still be in your budget to do something u want but dont have to pay up front.
I want to say it again that a lot of self control is needed if to use the credit card for installments and all.
i hope there are solutions to help those who need to clear the credit card debts and those who are blacklisted that need a second chance to clear the debts and restore the credit.
