No report/invoice? Or not information in the report/invoice?
+1.
As I previously mentioned before, cut micro-SIM have tendency of damaging the sim card slot (reader); But it maybe very rare; Your case may not due to the cut micro-SIM, but what I trying to highlight last time is that there is such possibility, so that's why I insist of not advising people to go for proper replacement, because if we recommend people to "cut", and then something happen, it's a big responsibility.

As I know, if the sim card slot (reader) is damaged, the whole motherboard needs to be replaced.
The longer it will be less value, unless you sell to those people who wants the N9. I've mentioned before, it's not easy to sell especially if delay longer, the spec is already dated (most people look into specs) and newer phones are coming out very fast.

If Pity, it's been a big pity long before N9. The N900 (Maemo5) was supposedly one of the best around back then despite it's spec is lower, but what it can do, what it offers, is what others can't. Not even N9 (MeeGo). Based on what it can do and what it offers, it could've been very successful but not enough effort was put into the OS.
As current N9, it's going through roughly the same phase as N900 back then... PR1.1, PR1.2; N900 stops at PR1.2, which takes a long time... N9 seems much better, in a way, where it got far far better OVI Store (ignoring the application repositories), and a word of the support up to 2014. The N900 (Maemo5) was like suddenly abandon, the OS itself is very incomplete, but they're working on Harmattan already? They don't even bother to complete the Maemo5.
Are you using proper micro-SIM or did you "cut"?
WP is inevitable, unless some "miracle" happen...
