Essentially those who have spoken up here already have the details.
GDP china has links to their website claiming to sell world of warcraft gold and delivery times of under 30 minutes. In addition, they even state that their fastest and safest method of delivery is to give them your account information (thank god I didn't.)
This company is seriously BAD news. After ordering 2000 gold, I recieved an email saying that it was on it's way. After a couple hours of waiting I emailed them asking for an ETA and they replied "2-48 hours." obviously I was a bit miffed: 2-48 hours? the link said most orders under 30 minutes. Of course when i brought this up in live chat the person "caroline" or somesuch said 2-48 hours is what 97% of their business occurs between.
Fine, I'll wait right?
24 hours hits and I get on again with a different chat person and ask what is going on with my order... they assure me the order is on the way and that I will recieve my gold as soon as they can finish accruing the amount. I look over their "about us" page and under point 2 under gold farming it says that if the order takes longer than 24 hours then a person can recieve a full refund "if desired."
However, I decide to give them the full 48 hours.
well, at 48 hours I still haven't recieved a phone call. I get on with livechat again (sally?) and say that unless they can get it to me ASAP I want a refund. She assures me that they will put a hot rush on the order and I'd be the first order they get out. I say that I'm going away for a day and that if the order is not ready by the time I get home, I want a refund. She said okay, and assured me it would be ready.
Well... at 96 hours I get home with no phone calls still. This time I get Evangeline who says "we are still getting your gold we will call you when it's ready." As if i haven't heard that one before. Well I've had it at this point and request a refund, and she says the order is almost ready. I tell her no thanks, and that, with 4 days, I could have accrued 2000 gold by myself with daily quests and a couple hours of farming easily (thus a professional gold-company should be capable of much faster turn-around no?). Well she tells me that if I want my money back I can "talk to paypal" and that her manager is not online. She then proceeds to log out of the chat and leave me hanging without any more offers to somehow resolve the issue.
Welp, here I am out my money. In the end, the money loss wasn't exactly huge, but it is the principle of the matter. I understand that paypal has trouble getting money back on "digital" items... but I intend to really push this issue and hopefully get GDP's paypal verification revoked.
In any case, if you are reading this hopefully it isn't a check-up on the website AFTER having made a purchase (and hopefully hopefully hopefully you DID NOT give them any of your account information). DO NOT make a purchase from this company... the 2 to 10 dollars you'd save according to their lesser and very bogus pricing is NOT worth any of it.
