So Tesla did not accept the payment, and tried to contact the customer to sort it out. Customer did not reply to emails, or respond to phone calls.
After some time, Tesla needs to get car back, so they do.
Once payment has been made in full, car is returned.
Obviously inconvenient and not ideal, but what should Tesla have done differently? They tried and could not contact the customer, for all they knew the person was deliberately trying to avoid them and keep the car without paying.
Would you expect any company to behave differently if acceptable payment has not been made, and the customer does not respond to contact attempts?
