I have been dealing with Spotloan, who was once known as Zest Cash, but is not a tribal lender. Several months ago I closed bank account and sent them a letter that I had overpaid and would not be paying them another dime. I received the typical emails, blah blah blah, and then about 2 months ago I received a letter from Stellar Recovery, a collection agency. Again, I sent them the same info that they were illegal, and didn't hear anything again. Now, I am receiving called from Lighthouse Recovery regarding this loan.
