I need to contact the referral program but I am unable to find any contact number or email. Today, I had 10 000 credits after referring my wife for a Model Y. I wanted to redeem for Model Y Liners for 3,500 credits and a Wall Connector for 5,500 credits. The app said there was a problem with the shipping address which was fine. I tried editing the address a few times then the order went thru. Then when I went to order the Wall Connector, I saw I only had 3,000 credits left. Obviously the order for the liner went twice with no confirmation before as it said: There is a problem with your order, try again later. It might have gone thru three of four times if I would have had enough credits. How can I tell them to edit my order for only one set of liners (All weather floor mats) and credit me the 3,500 credits, so I can order the Wall Connector. Thank you
