Hi, new guy here with a question. My Masterbuilt 800 gravity was delivered yesterday but its missing the griddle and the insert for the griddle. Ive tried MULTIPLE times to register my grill to contact masterbuilt but there is no way to get in touch with them. Ive sent them a message on instagram but they have not replied. If this is the way they do business, I don't even want this thing. Has anyone been able to contact them before I dispute this charge with my credit card company? Thanks Jim
