I have bought many keys with the help of gg.deals, never had any problems and that kind of made me to lower my guard when it comes to online shopping and potential scams.
That being said, there's no way this site is legit other than their professional design and having many payment options from all over the world.
I bought an activation code, which was already redeemed, both support and the seller, which I suspect are on this together and whole site is just a cover up for scams, gaslight me into situation in which I am the one that do not provide screenshots or information needed to resolve the situation.
I contacted rockstar games, for them to provide me with time and date of the code activation, but they cannot help me since my account is no being involved and I am 100% sure that the code was redeemed before me buying the code. I guess the only way to make Rockstar provide this information is to involve the police and ultimately get them to look into that shady site.
This is my open plead to anyone who was scammed by this site, don't just let them get away because it probably was a small amount of money, many small SCAMS add up to big numbers. So report that site to your local internet fraud departments.
Looking at the comments all over the internet I should've known better, but years of using gg.deals again, made me too comfortable with only shopping.
That's all, remember to double check or tripple check everything.
