Not in response to sharphamster, but by reading my previous post, I see that I might not have as clear as I thought. So for the sake of clarity

I'll try to do better this time.
When I use gmail, I don't get any email from Kobo because of the powerful, albeit sometimes overzealous, SPAM filter. They tried to reach me several times after my calls and I never got those emails. When they replied to one of my emails (I filled the online form), their replies went through.
So if you
call Kobo and give a
gmail address for any follow-up, beware that you may not receive the expected emails.
