Best products on a 20 year old panel door chocolate fire guard fart on that panel and it would fall in haha what a joke that customer well and truly ripped off!

Hi mate My lock just turns left to open door (top latch)...turning it to the right all the way should bolt the bottom latch shouldn't it ? Mine doesn't....so basically someone can reach in the letterbox and open the handle ?? Surely it is meant to bolt if y9u leave for the day ??
