answer:If it happened to me, no I would absolutely never pay a collection agency. If she wants to pay the actual phone company, she should call and discuss it with the billing department. Even then, I wouldn’t pay it unless an agreement was reached with the actual compnay that they would send a receipt for the payment and would cancel the debt collection. Collection agencies are a racket. Obviously the one that has bought her bill is persistent. If it were me, I’d report their tactics to as many local elected officials as I could to get some assistance in getting them to leave me alone.
