II. ANALYSIS
We review de novo the district court’s dismissal of a complaint pursuant to Rule 12(b)(6). Moore v. Voider, 65 F.3d 189, 192 (D.C.Cir.1995). A complaint should not be dismissed “unless it appears beyond a reasonable doubt that the plaintiff can prove no set of facts in support of his claim which would entitle him to relief.” Conley v. Gibson, 355 U.S. 41, 45-46, 78 S.Ct. 99, 102, 2 L.Ed.2d 80 (1957). Although we must construe the complaint in the plaintiffs favor, we “need not accept inferences drawn by the plaintiff^] if such inferences are not supported by the facts set out in the complaint.” Kowal v. MCI, 16 F.3d 1271, 1276 (D.C.Cir.1994).
The appellant first argues that the district court’s holding that the filed tariff doctrine requires the dismissal of her complaint is in error because she is neither challenging the reasonableness of MCI’s rates nor seeking to obtain a rate different from the rate in the filed tariff. In addition, Alicke contends that she has adequately stated a claim for fraud because she has alleged that MCI’s bills report that calls last longer than they really do and that MCI’s failure to disclose its rounding-up policy in its bills induces customers to use more service and to pay for service that MCI does not actually provide.
MCI’s first response is that the district court correctly held that the filed tariff doctrine bars this action because under that doctrine a common carrier has no duty to disclose its rates except in its tariffs, of which customers are presumed to have knowledge. MCI also argues that Alicke has failed to state a claim for fraud because the nondisclosure of its billing practice outside of its filed tariffs does not constitute an affirmative misrepresentation and because no reasonable customer receiving a bill listing the length of her calls in one minute increments could be deceived into thinking that every phone call she made terminated precisely at the end of a full minute.
We affirm the district court’s dismissal of Alicke’s complaint because the appellant does not therein adequately allege all the elements necessary for any of the causes of action she invokes. A claim for. common law fraud or negligent misrepresentation requires, among other things, an allegation that the plaintiff acted in reliance upon the alleged misrepresentation, see Pence v. United States, 316 U.S. 332, 338, 62 S.Ct. 1080, 1083-84, 86 L.Ed. 1510 (1942) (federal common law); Esteves v. Esteves, 680 A.2d 398, 401 n. 1 (D.C.1996) (D.C. common law); Hall v. Ford Enterprises, Ltd., 445 A.2d 610, 612 (D.C.1982) (negligent misrepresentation); and we assume that such reliance must be reasonable. Similarly, to state a claim based upon an unfair trade practice, the plaintiff must allege that the defendant made a material misrepresentation or omission that has a tendency to mislead. D.C.Code § 28-3904(e) and (f). Alicke has failed to state a claim for any of these causes of action because there is nothing in the way MCI reports the length of long-distance phone calls that could mislead a reasonable customer into thinking that she received more service than she really did receive and thereby cause her either to use more of MCI’s service than she otherwise would have or to refrain from switching to another carrier that bills for service in smaller increments.
MCI lists the length of each phone call in whole-minute increments — which, the court notes and counsel for Alicke confirmed at oral argument, is how long-distance service has always been listed and billed until some companies began recently to bill in smaller increments. Because no reasonable customer could actually believe that each and every phone call she made terminated at the end of a full minute, the customer must be aware that MCI charges in full-minute increments only. Accordingly, MCI’s billing practices could not mislead a reasonable customer. See Bootel v. MCI Communications Corp., No. 95-8270, memo. op. at 10-11 (D.C.Super. Ct. Nov. 25, 1996) (dismissing identical claim for unlawful trade practices based upon D.C.Code § 28-3904(e) and (f)); cf. Marcus v. AT&T Corp., 938 F.Supp. 1158, 1174 (S.D.N.Y.1996) (dismissing similar claim
