You can contact a seller advertising a product with the number, if the seller has chosen to add a number to be contacted on, or by sending them a direct message.
The seller will receive your message and will respond by phone or through the message they received.
While browsing the site, you'll find a variety of products and services. Search through the ads, choose the item you want and contact the seller.
