Schneck Appliance Service

I don't understand this complaint We did the best we can do on a machine that was poorly made, I never seen a gear case that would not come out of a machine We tried everything and even bought new tools and nothing worked And the customer never paid us anything for the work was
done We only charged him labor He still has a balance due of $ I have been in this business for over years and I know most of all machines and have never seen one built like this one
