Kingboost SCAMMED me out of All My Earnings

Warning to SELLERS/ BOOSTERS: Kingboost SCAMMED me out of All My Earnings

Hello everyone,
I am a staff member at FFShop, and we have been working as a game item supplier/ booster with Kingboost to sell currency and fulfill boosting services. Recently, Kingboost seized ALL of my unpaid earnings and cut off my communication access based on a completely fabricated accusation.

Here is the exact sequence of events, which I have full chat log proof to back up:

1. The Interaction: A user contacted me directly inquiring about boosting, so I sent them a registration link. The user then clarified they were an existing Kingboost customer.
2. The Immediate Refusal: The exact moment I realized they were a Kingboost customer, I immediately refused the order and stopped replying. I did not accept any payment, nor did I fulfill any service for them.
3. The scam: Two days later, before I could withdraw my hard-earned balance (~$400), Kingboost accused me of "stealing customers." They immediately locked my account and confiscated 100% of my unpaid earnings, despite zero proof of an actual transaction taking place.

Why this looks like a deliberate set-up / exit scam:

• The “customer” contacted me out of nowhere and aggressively brought up Kingboost immediately.
• Kingboost staff had full access to the chat logs. They knew I officially refused the customer, yet they deliberately chose to ignore the facts so they could have an excuse to keep my money.

My Advice: If you are an independent booster, currency seller, or studio, STOP WORKING WITH KINGBOOST IMMEDIATELY. They will look for any technicality or fabricate a setup to freeze your balance and steal your earnings. They do not treat partners fairly; they exploit them.

I have saved all chat logs with both the customer and Kingboost management to prove every word of this. Avoid this platform.

M+I had a great experience with…

I had a great experience with Kingboost. The entire process was smooth, straightforward, and exactly as described. My order was completed quickly, and the communication throughout was clear and professional. The customer support team was responsive and helpful whenever I had questions. Overall, a reliable service that delivers what it promises. I would definitely recommend Kingboost to anyone looking for a trustworthy and efficient provider.

Once again. They are the best there is!!

I have used Kingboost for almost 6 years now This is now my 4th expansion utilizing the services and boosters they provide. They are quick, provide a fair price. They often have sales for Mythic+ runs and Raids. The bundles are killer buy 3 get 1 free. I and my wife have geared up every expansion at reasonable rates and without any of the damn guild drama or loot drama. The boosters are professional and work with your busy schedule to accommodate you. The Customer Service team is helpful and if any issue arises, they resolve it quickly and make everything right. I have tried a couple other services here and there thru the years. After those experiences I am a devoted kingboost.net customer. There is a reason they are the best IMHO. The service they provide is just simply "THE BEST THERE IS".
