Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
Ok so this case was also complicated but this was in fact an activity win of sort since I based on the activity call done on July 25th and with the last message on Groudon's profile. Since there was a clear attempt at rescheduling I decided to let it slide and there was even a possibility of the games happening on Monday, conveniently I got busy and I couldnt bring round 2 until late at night.
Groudon PMed on discord (can screenshot for evidence if you want) about the situation saying that you missed the 2nd scheduled time which was yesterday. With 2 activity calls on deck, I decided to give Groudon. the activity call despite the extension request since everything was supposed to happen yesterday and according to the PM I received he couldnt accomodate to play today or Wednesday.
