Well, I received replies from 3 different Kobo sources.
I sent another request for support to Kobo Customer Care, just to have Glo #3 on the books. Sameer wanted me to send him the books on the device, so I've also sent him a .zip file of the device's contents, or at least what I can see from Windows. He promised to have someone contact me.
A few days later, Danny Staffieri emailed me. I'm going to go on the assumption that Danny is a male, but if I'm wrong, Sorry Danny.
He didn't indicate whether he was Sameer's contact or not, but I will assume that's the case.
He wanted my contact info so that I could return the latest Glo for analysis. Great idea.
A few hours later, I got an email from Kobo Customer Care, also asking for my contact information. So now I don't know if all parties are working in tandem, or the off-shore Kobo Customer Care has taken it upon themselves to replace it again.
Emailed Sameer and cc'd Danny, asking for clarification of who I should return this to, and to ensure they're both on the same page, but have so far not had a response.
I also mentioned that I would be amenable to getting a full credit for this Glo, and applying it towards the purchase of an Arc. At least with Android I know I have a choice of readers.
I will update the thread when I hear more.
