Regarding my complaint to Kobo about the black border around the text on the Touch -
Customer Care sent a follow up email: "We will assume your issue has been resolved if we do not hear from you within 10 days."
So I replied to tell them that I wasn't happy that it took a week and 3 emails from me to even get a response and that the advice to force a reset was ultimately a waste of time as the update was withdrawn from Touch a couple of days later.
I have now had another response, regretting that I feel their customer service isn't good enough and giving me a 50% off code (I hope it works!) for my next purchase.
I suppose if the tech side are still trying to solve a glitch then CS can't offer much help. Responding within their own advertised 24 hours to say they are working on it and providing details of how to return to the previous version would have been better. Or maybe installing the previous version is what the reset would have done at that point?
Well, I'm happy for now and once again, a big thank you to all the people who offer help and advice on these boards.
