I would echo those sentiments ScottishRosco.
Tesla site (when I placed my order) told me my car would be delivered in JUNE, nothing happened, then after ringing I was told the middle of JULY, then nothing happened, so telephoned again, told probably first weeks or middle of August...... nothing again....... long story short, I'm taking delivery next week BUT it really isn't good enough. Probably 15 phone calls in all, some waiting two hours plus on hold.
Customer service is very poor, and yes, Elon is trying to make things better now with the improved service team -better late than never. Thanks Elon for your input. I would ask that they simply KEEP THE CUSTOMER INFORMED of progress of their order and of course, remove unrealistic delivery dates from ordering pages. It would be simple to set up and automated email information service to tell the client weekly how their order is progressing.
Hopefully, time will improve the service (maybe with a little help from reading some of these pages by someone at Tesla!).
