Another update. Got a mail from Global Escalation Services and then a call today. Minor progress, but progress nonetheless. We ran through some troubleshooting - basic triage stuff that I was expecting - and he's now referred the call to one of the tech team to call me back - hopefully tomorrow. Why is this progress?
- He didn't fob me off straight away because the device is out of warranty.
- He didn't treat me like an idiot who has no idea what he's doing.
- He acknowledged the situation was 'unusual' - i.e. for us all to be suffering these symptoms since the firmware update. To be clear, this wasn't in anyway them accepting liability, but the acknowledgment that they probably can't feed this case into their standard flow charts and hope for it to be resolved is encouraging.
I shall of course keep this thread updated as and when there's any significant news.
