They can't even take a lollipop away from you! Let alone your kids! That's a crock! That woman is a lying 'tard!
You didn't defraud anybody, don't buy into that manipulation either. I used to work for a junk debt collection agency and the best collectors are also the best mastermind manipulators.
If she ever has the brass to call again. Hold down one of the keys on the dialapd and deafen her with that high pitched monotonous beeping. Also, don't pay this agency jack because twith tactics like these, they are surely not to be trusted with even one single digit of your bank account number.
You'll do fine by just remitting straight to the original creditor. Or you can seek out T&C. They're absolutely wonderful, they'll consoldate this, put those charlatans in theit place, and do well to temper all the outrageous "interest" and "fees" on this bill.
While debt is not something to shrug off, it's not something to freak out over either. You'll do fine! Everyone does.
