A charge from “SQ *STEPHANIE CASTANO” on your card statement likely comes from a purchase you made where she used Square as the payment processor—this could be an item bought from her online shop, a social‑media/marketplace listing, or a payment link or in‑person card reader tied to her account. In some cases, the business name that appears in Square may be her personal name rather than a separate shop brand, which is why you see “Stephanie Castano” rather than a store name. One‑time purchases are most typical, but you could also see multiple charges if you bought several items separately or paid in installments.
If you’re unsure about this charge, first review your recent orders on platforms where you might have bought from an independent seller (for example Vinted or other resale marketplaces) and check order dates and amounts against your statement. Look for email or in‑app receipts that list the seller’s name; these often show the payment processor as Square. If you still can’t match the transaction, contact your card issuer to request more details (such as the exact time, currency, and location descriptor) and to dispute the charge if necessary. Because this is a small independent seller without a central customer‑service center or corporate website, working through the marketplace where the purchase occurred and your bank or card network is usually the most effective way to resolve issues.
