This company is a SCAM TWICE now my device has told me that i unplugged my device (when I did NOT). And they then charged me $90. Your only option to fight it is to have a technician inspect the device (which costs you $150 of your OWN money). If they find nothing wrong with the device? You are out not only the $150 but also the $90. Should the device be defective? It’s not like you get your $90 waived and you’re good to go. No… you have to return to the shop when the new device arrives. Pay an additional $125 Installation fee… again out of your OWN money…. And the worse part is Intoxalox doesn’t reimburse your bank account. They simply credit your effing account. I know because I challenged it the first time. And just last week the new device gave the same error! I don’t have $275 to pay upfront so it’s almost easier to pay the $90 even tho I NEVER UNPLUGGED THE DEVICE I HATE THIS COMPANY
