About UN Tech
UN Tech is an Australian electronics retailer and refurbisher that sells a wide range of computers, laptops, monitors, tablets, accessories, and other IT hardware. The company sources business-grade and consumer devices, thoroughly tests and grades them, and then resells them at discounted prices compared to brand-new equipment. Operating from Melbourne and serving customers across Australia, UN Tech emphasizes quality refurbished technology backed by clear grading standards and warranty coverage.
A charge on your card descriptor such as “SP UN TECH CLAYTON” is most likely from an online or phone purchase made through UN Tech’s website or one of its marketplace storefronts (for example, a refurbished laptop, desktop, monitor, docking station, or accessory). Orders are typically one-time purchases, but multiple charges may appear if you placed more than one order, split a purchase into separate transactions, or if an initial authorization was followed by a final capture. Small temporary authorization holds may also appear when you first place an order or update your payment details, and these usually drop off after a few days.
If you don’t recognize the charge, start by checking your email for order confirmations from UN Tech or receipts from untech.com.au, as well as accounts on marketplaces like eBay, Amazon, Kogan, Back Market, or Reebelo where UN Tech also sells. Log into the relevant account and review recent orders, payment methods, and invoices. For further questions, you can contact UN Tech via the contact details on their website, quoting the transaction date, amount, and the last 4 digits of the card used. If you still can’t match the transaction, contact your bank or card issuer to dispute or block the charge while the investigation is underway.
