It doesn't necessarily have to be cold pressed to work, there are a variety of other methods of processing the oil that are just as effective. If you want to be picky and want it specifically cold pressed (the traditional method) and not processed any other way, keep looking there are companies that still use that method out there. Maybe they all just don't bother printing it on their bottle labels, just look at the company's website.

However, if you are concerned that the product you bought is inferior, just email the company and ask how it was extracted/processed.
