Additionally, the security deposit you used to obtain the card is used if you were to default on your payment. However, this is not the case if the balance in which you have defaulted happens to be higher than the security deposit amount. Using the security deposit means that even if you default, the card will be paid because it is secured by your funds and you will not have the account end up in collections due to nonpayment.
The best way to handle this is first pull your credit reports from the three major credit agencies – Experian, Equifax and TransUnion.  And this can be done free of charge once every 12-months through the site Go through each of the reports as thoroughly as possible looking for any inaccuracies, like – incorrect information on collections, judgments, balances, new accounts, and payment history.
Next, estimate your monthly spending habits for other expenses such as gas, groceries and entertainment. Create a limit, based on your income, of what you can spend in each of the different categories of expenses. For example, if you tend to spend $400 a month on groceries, try to stick to $300 a month on groceries by making changes like buying generic brands, using coupons, and resisting impulse purchases.
