I'm sure they'd replace it for you, I bet they'd be horrified that it broke, I've never had an itti break on me, so definitely take it back if it's convenient for you hon! Otherwise you can email them to let them know and they'll get you to send it back to them.

Either way I'm convinced they'll replace it, I've found Itti Bitti customer service to be really lovely.

What a pain, we love our ittis, so I'm sure you will too, once you get this sorted! Found a number too on this page, but I didn't cut and paste the number in case it's also her private mobile, though I can't imagine it would matter too much. Good luck!
