Ask your money back or ask the wow gold suppilers check the stock every 30mins !
Most wow gold sellers in china ,there are about 100k farming wow gold everyday ,after get enough wow gold,their will sell them to suppliers, then,all wow players can buy gold from suppliers .When the ppl who need some wow gold on a site and ask :"hey do you have some stock on my server ?" Most companies will said:yes we can provide you enough gold and delivery in 15mins " so the player paid and waiting for the gold delivery .
BCZ some company told them have the gold that is not the true ,bcz they should check the gold farmers whether have stock or whether have stock in their bank. Stock changed every mins ,because there are so many ppl orders and sometimes blizzard closed the farmer accounts or banned their bank accounts, so the stock was gone !For this issure the buyers should wait maybe sometime should wait for somedays or some hours !
Make a complains to paypal ,ask your money back or ask the wow gold gold suppilers check the stock every 30mins ! Or you can choose a good site to buy wow gold .I think this is the most important thing.
