My macbook pro won't charge due to an electric shock

My macbook pro won't charge due to an electric shock that was caused from a charger that was in a bad condition, the computer didn't turn off when it happened but it stopped charging. When the battery died it refused to charge with any charger, I even bought 2 new ones. I sent it to apple and they are asking $650 for fixing it! The problem is that the macbook is only a year and a half old and I live abroad where there is no apple branches or any of that. I had to send it to the USA first. Also, I might lose everything saved on the macbook after fixing it! Any solutions? please help!
