Customer Support - 1800 646 952 Option 2 . Got through within a couple of minutes (10am). Said I wanted to activate FSD on my model 3. They took my credit card details and said they will relay request. Activated 2 days later - no email or phone confirmation - Account Manage tab updated car details to Full Self Driving (Autopilot removed).
Did this and it was added the same day (today) by the time I got back to the car.
I’m amazed I just dropped that much cash on a software feature and a promise
At least I paid less LCT.
