I purchased a 1 hour service subscription for my Model S using the Safari browser on my desktop and none of the pages would open. I then logged in on my Chrome browser but, of course, the site did not recognize that I had already purchased the session and asked me to purchase one. At that point I spent the rest of the hour changing settings in Safari to no avail. At the expiration of the hour I purchased another hour using Chrome and it worked flawlessly. I replied to the email congratulating me for purchasing the first hour using the questions or help link and got a canned response to log into my account. I did that and sent an email explaining the situation and asking for a refund of the first hour and got a response that Tesla would be " reaching out to me soon. " Since that has not happened and I can't find a phone number anywhere to call customer service, I am thinking about disputing the charge on my credit card to get someone's attention. Has anyone who uses the service site ever had this experience? What does everyone think, will Tesla then get ahold of me to discuss the situation or will I just banned from ever buying another service subscription?
