Finally, after waiting for so long, I finally got a bonus of $5, with only a $20 wager. I was so happy to receive this letter. In my last bet, there were 2 teams that lost out of 11 teams. My prediction was indeed bad. The match I was really looking forward to was Fulham vs Manchester United.

When did you actually receive the email for the first time? Have you completed the wager within the given time frame? If yes, then submit a complaint to a mediator (Askgamblers). This is one kind of scam if they aren't giving the bonus which they promised. Because you were required to take risks by making a deposit.

I have attached the video link in comment #23216, because we talk too much in live support, I cannot capture too much.
And the conclusion in the link talkimg below. I hope you can see it

I will advise that you don't conclude yet on being scammed, however, you may need to repost on your image correctly on the image hosting site that could show the evidence clearly on what you wanted to share with us, you can make use of talkimg.com for this purpose, you can see that we cant see what you posted here, which should have helped in getting the right information or direction to take on the issue you had on the platform.

There should be have some details in Emails.

Usually is 5 days, just check your emails first and sometimes they using their own time server or their time zone not yours. So, even in your country already at least 5 days in their time is not.

First you can check the emails for the details rules, and second try to give a little bits 1 days extra for the estimation.

Or, you can contact support with BK8 Telegram for each country. In my country, the telegram support for Indonesia: https://t.me/bk8csid. I choose your Country (VN) and direct me into: https://t.me/CSKH247BK8.

They have a few contact person depends on the regions of site they was running, to make it easy for the user.

Have you tried to ask in 'Live Support'

They can give you more fast response rather than in here, I been given some mirror link once on the live support at the time have some problem login in BK8BTC. They really have so many mirror link for the website.

The problem, all of these mirror link is not being stated in term & condition or guidelines. So you need to ask first for confirmation, to avoiding leading into phising site.

Only if there is something up with your account or in cases where there was a big win sometimes.
Under normal circumstances you don't have to go through level 3 and 4, normally not even level 2 but obviously this is changing from next January.
And, there is no stake support here. The rep hasn't been see for a while now so you better ask the official live support on site or (if you have one) your vip host via telegram. You can also ask your questions in the official stake forum and maybe some mod can answer it for you.
