"[I]n the case of any successful action to enforce ...

An award of attorneys' fees pursuant to section 1692k(a)(3) is mandatory. See Graziano v. Harrison, 950 F.2d 107, 113 (3d Cir.1991) ("[A]ttorney's fees should not be construed as a special or discretionary remedy; rather, the [FDCPA] mandates an award of attorney's fees ...").
