Oddly enough, just rang 150.
Been told that I have triggered the STM (not really a surprise, I was expecting this). I asked the question why it was still STM'd at 8am this morning, and for so long, even before I uploaded, and the advisor, and his Lvl2 didn't have an answer.
Been advised to keep it off overnight, and see if the config resets in the morning. Tried this before, but, worth trying again. And if this fails, 150 again tomorrow night.
First time, oddly enough, I have been taken to someone (on the indian centre) who actually didn't jump straight into the script. Quite pleasantly surprised
