If you are less than 180 days delinquent, meaning that your account has not been charged off yet, you can simply call your credit card company (their phone number is on the back of your card) and tell them that you want to make a payment. Keep in mind that because your account has gone into collections, you have some leverage, and can negotiate with your credit card issuer to get them to waive fees, lower the interest rate on your account, offer an affordable monthly payment plan, oreven settle for an amount less than you owe.
If your account has been charged off (i.e. more than 180 days delinquent), it is likely that your credit card issuer has sold the debt associated with your account to a third party – i.e. a collections agency. Therefore, you need to call back the collections agency that has been contacting you. You still have leverage if you want to pay the debt off, and can negotiate with a collections agency the same way you would with your credit card issuer. A collections agency may also be willing to put you on a monthly payment plan, similar to what you were responsible for prior to your account being charged off. As you decide how to best handle your credit card debt with any collections agency, remember that they will continue to harass you until you satisfy the debt or make arrangements to do so.
