Our brand new commercial ice machine was giving an error and would stop making ice. It was under warranty and Manitowic sent us to this company. They require you provide a credit card before they send a tech,. They sent a tech who restarted some things, suggested we change our filter but didn't actually fix anything. Charged us $461. The issue happened again a few days later. Sent a tech who "cleaned a filter and changed the ice thickness" waited for it to make ice and then left. Now it's making ice but not draining. Charged us over $500. Get the red service wrench error again, call them to say they've charged us over $900 and haven't fixed the issue and they send repair guy who said can't do anything but clear the drain as it's making ice with the service error still displayed. Charge us over $300. All this with a brand new ice machine that under warranty. Do not use this dishonest and greedy company. We're now using a different company and having our bank fight to get our money back: total scam going on here
