No customer service. Trying to track items purchased. Email invoice has no tracking number for shipping. Call or email this company, no reply despite promise to contact within 24hrs. Calling 800 number redirects you to another company (Toner Clinic) where the customer service is the same. I would avoid at all costs. Glad I only made small purchase, as a trial, and payed through paypal. Will be contacting paypal if order is a no show.
