Amazon India — amazon account hacked

Due to my utmost surprise my amazon ac hacked and new email i'd set for the same account. I am not able to login from my email id now as it shows not a registered email i'd with us. And top of all amazon don't have any customer support no where i can speak directly to them about my problem. Only option i have now is through mails. Since whole day i m trying to locate customer care nos but unable to do so bcoz no available on net has of no use bcoz they only suggest u to go on portal for ur problem. Please resolve this matter as i have to get block my credit card for same.
