OPINION

Pro se appellant Cazzie Williams appeals the District Court’s order dismissing his complaint under 28 U.S.C. § 1915(e). We have jurisdiction pursuant to 28 U.S.C. § 1291 and exercise plenary review over the District Court’s order. See Allah v. Seiverling, 229 F.3d 220, 223 (3d Cir. 2000). For the reasons set forth below, we will summarily affirm the District Court’s judgment. See 3d Cir. L.A.R. 27.4; I.O.P. 10.6.

In 2003, Williams pleaded guilty in the District Court to four counts of bank robbery, and the Court sentenced him to 156 months’ imprisonment and ordered him to pay $105,797.85 in restitution. Williams filed a notice of appeal, but then withdrew his appeal before briefing.

Williams has since sought to attack his conviction through collateral proceedings. He first filed a motion under 28 U.S.C. § 2255; his central claim was that his plea agreement was defective and that his criminal judgment was consequently void. The District Court rejected this argument on the merits. See Williams v. United States, Civ. A. No. 08-1242, 2009 WL 2191178, 2009 U.S. Dist. LEXIS 62725 (D.N.J. July 22, 2009). Williams subsequently filed a petition pursuant to 28 U.S.C. § 2241 advancing a similar challenge to his plea agreement; the District Court concluded that Williams’s claims could be pursued only in a § 2255 motion, and thus dismissed the § 2241 petition. See Williams v. Zickefoose, Civ. A. No. 10-2953, 2010 WL 5479621, 2010 U.S. Dist. LEXIS 139069 (D.N.J. Dec. 29, 2010).

At issue in this appeal is Williams’s most-recent effort to vacate his criminal judgment. He has again argued that he was convicted based on a flawed plea agreement. Therefore, he contends, his incarceration and the restitution award are unlawful. However, he has framed this proceeding as a civil action arising exclusively under the Fair Debt Collection Practices Act (FDCPA), 15 U.S.C. §§ 1692-1692p. He seeks his release from prison and $390 billion in damages.

The District Court dismissed Williams’s complaint, concluding that “[rjegardless of how Williams characterizes his pleading here, there is no doubt that he is actually challenging the validity of his conviction.” Op. at 13. Williams then filed a timely notice of appeal.

This case requires little discussion. Absent a waiver, sovereign immunity shields the United States and its agencies — including all defendants named here — from suit. See FDIC v. Meyer, 510 U.S. 471, 475, 114 S.Ct. 996, 127 L.Ed.2d 308 (1994). Consent to suit “must be unequivocally expressed” in statutory text, and cannot simply be implied. White-Squire v. U.S. Postal Serv., 592 F.3d 453, 456 (3d Cir. 2010) (internal quotation mark's omitted). Congress did not waive the sovereign immunity of the United States in the FDCPA. See Wagstaff v. U.S. Dep’t of Educ., 509 F.3d 661, 664 (5th Cir. 2007). 1 *144 Therefore, the District Court properly dismissed the complaint.

We also deny Williams’s request to recover his docketing fees. Williams filed a complaint and an application to proceed in forma pauperis; 28 U.S.C. § 1915 makes clear that filing fees shall be assessed, and makes no provision for a refund of such fees. See § 1915(b)(1); cf. Porter v. Dep’t of Treasury, 564 F.3d 176, 179 (3d Cir. 2009).

Accordingly, we will summarily affirm the District Court’s judgment. 2 See 3d Cir. L.A.R. 27.4; I.O.P. 10.6.
