I have left so much money in account to cover the renewal of my domain that I have used for more than 10 years. Today, I noticed that my domain had expired and that the balance had disappeared.
I contacted them, they refused to refund my money or renew the domain, they suggested to transfer the domain elsewhere.
I hope that even is expired, I can still transfer, but the point they stole my money.
Know who you are giving to or where you store your credit card details, but at Enom, do not store anything.
