Clearly this whole increased communication around waitlist positions and proactive updates has been an utter failure. Instead of focussing on that - how hard would it be for you guys to have an open sheet which shows some unique ID (subscriber ID?) and their position? I don’t know why this should be a huge complex manual activity - you literally have a list of IDs, and when people get their cars you update the status to ‘issued’ or something.
Again, this list should take 10 seconds to update when you get your new cars in - this isn’t exactly rocket science that requires recalculating everything, unless you have some critieria where people can jump the queue and you don’t want that to be made visible?
It would also mean you don’t get daily calls from customers asking for updates.
