Cintas Corporation review: Faulty fire suppression equipment and charges

We have a Restaurant in Katy, TX in which Cintas provides our Fire suppression equipment for. This is the wet/dry powder chemical that disburses white powder when there is a fire in the kitchen. This system has gone off two times in the past two years with most recent last month and previous on July 4th last year;when there has been absolutely nothing wrong and no sign of any sort of fire or high heat. By this equipment going off, it disbursed white powder all over the kitchen, all of our equipment, food, etc. which means we have to shut down the restaurant immediately. Once we shut down, then Cintas comes in to clean up and recharge the wet chemical system along with charging us those fees they also pass along a service call fee. This ends up being a charge of over $4,000! This doesn't include what we lose in lost revenue, wasted food, upset customers, and employees that lose wages as well. When we try to address this issue of faulty equipment and overly sensitive system with Cintas, and ask why it would go off without reason, they just adjust the temp setting and say it is no fault of theirs. We even captured and saved video footage showing the time this past month when the system just went off on it's own causing extensive damage and it shows there was no fire or no reason it should have gone off. This is no way to back up your product,or take care of your loyal customers!
