I purchased a 2017 Model S from a private sale. It had unlimited supercharging according to Tesla prior to my purchase I also read all the posts and news articles regarding the new lifetime policy and my car definitely fit into that category. Today, after owning the car for more than 3 months, I was charged for charging 8 times over the last week. I phoned Tesla and was told that my car didn't qualify for lifetime supercharging because it was originally purchased using a referral code and referral codes lifetime charging is not transferable. This doesn't seem correct at all. The only reason a referral code was used is the car was purchased just before Tesla made the final lifetime policy. Someone there please tell me that this billing is a mistake, I love my Tesla but I'll sell it and sell my stock next week if this isn't corrected. This is a true care of bait and switch. I honestly believe that this is just a mistake made by the billing department. PLEASE HELP!
