Hi guys I would like to ask and see if anyone bought Razer Pin from E-Pay before?

Yesterday I bought 6 Razer Pin from E-Pay using GrabPay and everything is smooth until one of the PIN failed to reload on Razer website.
I tried contacted Razer and they told me the pin is USED but not used on my account and they ask me to contact authorities for this matter.
I tried contacted E-Pay side too and they told me they need time to check and see if it system issue so I have to wait 2-3 days

Anyone has this problem before? How come Pin can be used by other people? Or is it because of the timing same time purchase then system give 2 people the same pin?
What if E-Pay side can't help saying that Pin already used? Do I have to lose the money?

Razer Pin? You mean Razer Gold Pin? Please do not confuse Razer Pin and Razer Gold Pin.

Ya Razer gold pin

If the pin is just randomized numbers and letters (without symbols) and it's quite short (ie 9 or 12 numbers) and razer did not protect their end to not receive so many tries at one time, easily a "hacker" can just spam Razer's server to test all sorts of combination. If that's the case, unfortunately, your pin was easily guessed (is the pin something like alphabets and numbers just next to each other like efgh6789ijklm) and the "hacker" picked it up. Well, it's up to e-pay to decide if they willing to give you back your money or give you another pin.

Looks like this is Razer problem then I am afraid that E-Pay just gonna ignore this issue
