I asked them to show exactly which bets used my real balance and they provided two bet IDs but those two bets are NOT losses.
Please post a screenshot of your Bets. It would be even good if there is a way to share your bet IDs through a link which lead to the platform itself to remove any doubt.
I deposited around $600 and started betting immediately. Right after depositing, my balance showed around $900. So apparently a bonus of around $300 was activated, which I did not intentionally select or realize at the time. I was confused by the higher balance but assumed I could just bet normally. I then placed my first bet of $750.
How could you not realize an extra $300? If you have deposited $600 and chose to bet with $750, you are clearly aware of the additional funds. You should have contacted customer care immediately after deposit.
