Plant City Lock Key

I purchased a safe two years ago I have never had the thing openI returned to the store with the safe that does not work and he wants more money
Two years ago Steve asked me aht combination I wanted on the used safe he was selling meI told himI have never had any luck getting the thing openHe insists that the combination is wrong but he is the one who installed itthe unit does not workhe wants two hundred to open it and four hundred for another safeThis is a rip off as the unit does not work he does not stand behind the products he sells
