giftcardzen.comは安全ですか？

I bought two $100 ebay gift cards that i have been collecting for galaxy s8 and a few months later the codes balance was at $0. Be cautious when buying giftcards, sellers can use the code for themselves even after you have the code. Make sure to spend the money on the codes after 100 days of buying it because after that you can not get refunded by the site. I surpassed the 100 day period and can not get my money back. The ebay seller of the codes stole my money. I would still buy from this site but i will use the codes right away and not leave them saved for later use.
