Hi Helene.
Just 2 questions:
1. did you deactivate the option when you stayed in France? If you didn't do it, I think that you risk to have a 'under 0' balance

And you have a big debit with Wind it's better to buy a new simcard than refilling the old one
2. do you want to use "Mega No Limit" in Italy or abroad? If you use the option in Italy no change for you, if you use it abroad you had new prices from December ->

If you need an international data option "Mega No Limit" is not more the best solution...
