My account has been debited 2 times for 99USD, can i get refund of 99usd?

We are fellow users, so nobody on here can potentially refund you.

What shows on the account's purchase history ? Is one of the charges only : About payment card authorization holds in the iTunes Store - Apple Support ? If it does show twice contact iTunes Support and see what they say : Have you checked your iTunes account's purchase history (and family members accounts if you are a family organiser in family sharing) : http://reportaproblem.apple.com or http://www.apple.com/support/itunes/ww or https://www.apple.com/emea/support/itunes/contact.html
