OPINION

Rajaee A. Pooler appeals the district court’s order granting Supervalu Holdings, Inc.’s (“Supervalu”) motion to dismiss his complaint as untimely, .pursuant to Fed. R.Civ.P. 12(b)(6). This court reviews a grant of a motion to dismiss de novo. Mayes v. Rapoport, 198 F.3d 457, 460 (4th Cir. 1999).

Pooler first contends that he timely filed a charge of discrimination with the Equal Employment Opportunity Commission (“EEOC”). We agree. In his complaint Pooler alleged wrongful termination and disability discrimination under the Americans with Disabilities Act (“ADA”), 42 U.S.C. §§ 12101-12213 (2000). Accordingly, Pooler had 300 days from the alleged discriminatory act to file a charge with the EEOC. See Tinsley v. First Union Nat’l Bank, 155 F.3d 435, 440 (4th Cir. 1998) (citing 42 U.S.C. § 2000e-5(e)(l) (2000)). Because Pooler did not receive unequivocal notice of his termination until June 13, 2002, we hold that his wrongful termination charge, filed with the EEOC on October 29, 2002, (138 days later) is timely. English v. Whitfield, 858 F.2d 957, 962 (1988). To the extent that Pooler wishes to challenge Supervalu’s December 20, 2001, request that he return to his regular duties, we hold that this claim is untimely because Pooler failed to'file this Charge with the EEOC within the limitations period.

Pooler also contends that he timely filed his complaint in federal court within ninety days of receiving his Right to Sue Letter from the EEOC. We agree. Because Pooler expressly relied upon the district court’s order directing him to file an amended complaint by April 21, 2003, and because the amended complaint relates back to the original complaint, which Pool-er timely submitted to the district court (albeit not filed, at the district court’s discretion), we hold that Pooler’s amended complaint, filed on April 14, 2003, was timely. Panhorst v. United States, 241 F.3d 367, 372 (4th Cir. 2001).

Accordingly, we vacate and remand for proceedings consistent with this opinion. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before *964 the court and argument would not aid the decisional process.

VACATED and REMANDED.
