Where can we verify the starting time that you mentioned here? I was also trying to find out the exact start time of those matches. But I only managed to find out that some of those matches started before 10:00 AM EDT, while some other matches started after 10:00 AM EDT. Two to three matches were played on the same court number. Which proves all the matches didn't happen at the same time. Bookmakers were indeed showing a generic time. Maybe OP has already verified the game start times and accepted the decision of Roobet.
I was allowing Roobet some time to review it as they said they would but they just got back to me saying not only will they not go ange my bet result but won’t even compensate me anything. This is exactly right, many of the matches were on the same court so the 8am start time is just a generic start time but many matches started after 10am but Roobet refuses to see this.
