Apple farms it's loans out to other companies. Apple does not manage them.
MBNA is one credit issuers, and has a leniency policy that includes doing anything it can to screw you. Technically you agree to the screwing. If you miss a payment, your rate may go up to %20 or greater, userary!!!! They routinely shorten payment periods, so instead of 30 days, you might end up with a 25 day grace period. And this shortening may happen with you being a good loan candidate.
Something to think about is either a personal loan, or a secured loan. Personal loans are given rarely, but are worth applying for. The interest is usually fare, but the repayment period may be short, around a year. The advantage is that your credit score will improve much better with a bank loan v.s. Revolving debit, like a credit card. A secured loan is weird. In the end, you end up loosing money, but it works this way. You deposit all or part of the money, and the bank gives you a loan, secured against what you have deposited. Why would one pay for the privilege to borrow money? The interest rates are generally lower and their is usually more flexibility of payment plans. Other advantages are when your done, you have cash in the bank! Also, your credit score improves.
MBNA can and will destroy your credit rating if you falter at all. They will sell your "debit" off to debit collectors that use awful techniques to get their money. Often, they will lie, break the law(heck your a deadbeat- who can trust you) and omit what ever information they can to get as much money out of you. A common tactic is to have you agree to pay a small amount, like 20$ on an ATM card, and then they take out a larger sum on a regular basis. I can relay stories from my friends, if you wish.
Credit is a commodity, do you can to improve your score, but don't get your self in needless debit. Analyze weather you spending money on a need or a want.
Cheers!
