I have tried for over three hours to speak to customer services, no one available, the air sprayer has a rubber seal missing for the return tube connection, my kitchen is beingfitted in 4 days, and I need to spray my kitchen,living room, dining room, ceilings and walls, I'm very dissapointed to have no help to fix this problem, it's a useless item without the connection. Very upset to be left without what I need to actually use this machine!!
