The salesman promised my elderly disabled parents a door that could be unlocked without having to take the keys from their pockets. What he didn’t tell them was that they needed a smart phone in order to do this. My parents do not own smart phones and had they known would not have bought this door and lock. CSJ are only prepared to change the lock at my parents expense despite the fact that the salesman misled them. My parents now have a front door that they cannot use. In my opinion scoring this company 1 out of 5 is generous, had there been a lower score I would have given that instead.
