We placed our deposit for the Model 3 on April 20th with the Tesla Service Center/St. Louis & were told we'd receive an acknowledgment from Tesla within 48 hours. It will be two weeks tomorrow & still have not received. Have contacted the Service Center & told that Tesla acknowledged receiving our deposit. I'd feel much better if I had something in writing from Tesla other than just knowing they have my money & do I have a place in line or not?
