The part that attaches to the front of my Aqua Fizz machine, about the bottle container, was not included in the box when I received the machine. How do I replace it?

Please ship me the part and one additional cartridge.

I think I answered this already, but just in case……I would like to purchase the part that attaches to the front of the machine above the bottle receptacle, and another gas cylinder.

Please do not duplicate this order.
