Hi AllAroundAQHAer
Welcome to the forums.
While you requested Capital One to close the account sometime back, did you place a written request and return the card to them? If it is not done like this, most of the credit companies do not consider closure of the account. In that sense, the additionally charges are tucked on to the account until it is paid off.
Since you made an online payment to Capital One and they have accepted it, this means that your account is perhaps not sold to any outside collection agency. This also signifies that Encore is contacting you on false reasons. They may have got your contact information but they are not having any knowledge about the accounts. If so, ask them to validate the debt as it is your legal right to know the complete details. If they can provide you with complete debt validation, you can dispute with Capital One about them accepting payment from you. But right now, it seems that your account is with the creditors only. And the collection agency is trying to make money from you.
Deal with Encore using your federal rights guided in the fdcpa law. Request for a debt validation if they are holding your accounts. (Samples of debt validation letters are available in this forum).
Also mention in your letter that they are required to stop all collection activities until your debt is validated and you refuse to be communicated by phone. Leave some space to be contacted through mail only. This way, you won't completely cease and desist the collection efforts and you will be informed if they intend to take any legal actions against you. Though, they don't have base to do so.
Once they have received your letter, they are required to stop all collection activities. If they do so, it will be a violation of the federal rights and you will be in charge of taking legal actions against them with the help of your lawyer.
In that case, you will also like to record the phone calls and inform the caller that you wish to present it for legal actions against them. I suggest you to exercise your consumer rights so that this collection agency remains in the best of their behavior.
Hope this info comforts you a little and makes you feel stronger.
