I dont think its very often of us to leave the game and connect the chat before we increase the bet. i have attached the screenshot showing that my spins are not deducted from the bonus balanceThat particular group are very quick at making payment and I doubt whether a $7k would be an issue.
You mentioned that you had finished your wagering.
It is very easy to find out exactly how much wagering has been completed, personally I would frequently check on the account page.
Also before I would increase my betting I would also get confirmation from live chat that wagering was complete.
Maybe its me but if I had a balance of $7k and wagering to complete I would be checking the wagering requirements multiple times over. I certainly wouldn't be nonchalant and make assumptions.
The file was sent to me from them.
