Pinnacle Credit Services is a collection agency. You would not have opened an account with them. They are likely collecting for a credit card. I do credit counseling for a nonprofit agency and they are a common collector. If you contact them, they should be able to tell you who the original creditor was, but typically that information will be included on your credit report. Make sure you are aware of your rights under the Fair Debt Collection Act as well as Fair Credit Reporting Act. Best source for that is the Federal Trade Commission or FTC.gov. Good luck!
