During the consultation our instructions for how our units should operate were not followed or passed on to the construction personnel so we ended up not receiving the type of units we requested. This resulted in further complication in what appears to be a design fault as when keys are left in the lock damage occurs very easily. I know that you add labels to warn customers but this should be designed out so it cannot happen make it idiot proof. This has all resulted in costing more to our original budget which should not have been the case if clear instructions on how the build should have been as then damage would not have occured. Certainly lock design needs to be looked at as they should never be were the door folds are. The actual installation was very good and efficient and the installers very courteous.
