I just contacted Microsoft support on my Lumia phone via the preinstalled "Contact Support" app, about an issue of the language of comments on apps in the Store being in the wrong language (different from my device language, and different from my account's country). After pinpointing the cause of the problem, they said I should just change the region under the "Time and language" section.
But before I left the support chat, they asked me for my email address to "confirm", even though they admitted that they can see my email address from the account I'm contacting them from. They wanted to send me more information about what I can try if this doesn't help. I gave them my email address.
And then they said that they also need my IMEI. Which was weird, so I just left.
- Is there any reason they should actually need my IMEI for this kind of rather simple problem with a simple solution? Is it standard routine?
- Is there any chance that the Contact Support app was compromised on my phone and I didn't actually end up in Microsoft support?
- What is the worst thing someone can actually do with my IMEI? Am I overreacting?
(also, right at the beginning of the conversation they asked for my phone number. I asked why. They said it's standard practice if we lose connection, they will call me right back. I said it seems intrusive, and I'd rather not give it to them. They immediately apologised, and carried on with solving my problem)
