My two penneth, if I may.
You have been there less than 12 months. They don’t need a reason to let you go.
“Sorry Mr. Mog but things just aren’t working out and we feel it’s best yadda, yadda, yadda. Of course references will be given etc…”
This is how it so easily could have gone. You, if I may say, have handled the pressure very well and demonstrated a very high level of professionalism both in the way you provided evidence and the way you accepted responsibility where necessary. Getting an extra 3 months is a massive result in my opinion. Of course, what you do with the time is up to you but I am genuinely very pleased for you.
Well done sir!
