i upgraded my model S 60 to the 75 for the $2,000 price this morning at 9:00 am. It is now 5:00 pm and my car is still a 60. MY Tesla shows its a 75 and my bank account was also billed. I called Tesla customer service and no joke...this is what i was told.. Customer service agent " go to controls. Now tap Settings. Now tap units and format. Now change rated miles to ideal. Okay sir do you now have more miles on your car?" WOW! I explained to her again what i was calling about and that im not just complaining that my car doesnt have the mileage it should. Long story long...how long did it take you all? All ive read is that it takes 5 minutes. The email confirmation i got says "it may take up to one hour"
