Titanfall 1: I need 3 games to unlock Custom Match in Frontier Defence

Titanfall 1: I've just started brand new to playing T1. I can play solo by using Custom Match in Frontier Defence. To unlock Custom Match however, I need to first play 3 matches. I cannot find 3 other players to play so I'm asking an EA Tech to please put a tick in the box that says "Played 3 Matches" or "Unlock Custom Matches" or what ever it is. I cannot do this since the config for T1 is not held locally.

Please help or let me know if this is doable. Thanks.
