Hi all. I took delivery of a Model 3 on 5/18. I've never received copies of the trade-in documents and I don't think I've ever received an actual bill of sale for the purchase. (I have a couple of "sales agreements" but they don't show a completed sale.) Yes, I've looked at "documents" on the web page and the app. Trying to contact Tesla through the app or the web page hasn't produced results. Has anyone experienced this or have any advice? Thanks.
