Well, I called at the time of installation & talked to Ben, when I placed the order I missed the lock & sent a following email within 5 min (which it seems you have a note of but took no action? I also informed you that the 6mm armoured cable was supplied by me (15M) as I have an electrician working on site and it suited me so all the inlets to the hose were made together. On the paperwork I was still billed for 15m, Ben offered a logical solution: credit the cable re-invoice the lock - this was not possible, he asked for this to be authorized - this was deigned, also I was not granted access to the person who could make this decision, so now I've over paid for the cable and I have no lock. Please resolve this. The installation is only Ok, this could also not be resolved with the fitter.
