Our customers know: you don’t mess with a Shark. BILLSHARK not only takes a bite out of your bills, our Sharks act as enforcers by keeping an eye on slippery tactics from the big guys. If a service provider goes back on their promised savings from a BILLSHARK negotiation, we’ll sink our teeth into them and get you the deal we negotiated from the start. If we can’t fix it, we will refund your savings fee in full. That’s the BILLSHARK promise. Read more about Our Guarantee in action.
