Under FTC's Mail Order Rule, sellers must ship within 30 days--or notify you of delays. Dispute credit card billing errors in writing within 60 days of your first statement; issuers must resolve in 90 days (up to two billing cycles).

Understanding Online Purchase Disputes and Chargeback Basics

Online purchase disputes arise when buyers claim "item not received," "defective," or "not as described." Chargebacks reverse charges via your bank under the Fair Credit Billing Act. FTC's Mail Order Rule mandates 30-day shipping for online orders. Banks follow a process: dispute filing, chargeback issuance, merchant response, and decision (Chargebacks911).

Stats: Chargebacks up 20% yearly; 75% fraud losses (Sift); >1% rate flags high-risk merchants. Buyers benefit from bias; merchants must prove fulfillment (Signifyd).
