Hi kannikar,
Thank you for your post and welcome to the forums.
I am really sorry to hear about what has happened here. We would only be able to bring the number over to us if the account was still active, which I can see from your post it isn't. I will send you over a private message to see if there is anything I can do - I can't make any promises but I can at least try 🙂
Cheers.
