My opponent contacted me the day matchups went up and I responded to him within a few hours of him contacting me to discuss our availability. He never responded to what I asked and it had been a week so I messaged again on Sunday listing off some more possible availabilities for me. He never responded to either post and his profile showed he was online within the last day so he was capable of responding to one/both of them.
Calling activity due to the lack of a response from my opponent.
