Sadly
@Colin ********
this appears to be a self inflicted problem (meaning you applied too close to when you were coming here)๐
The visa itself is valid for three months <- meaning you have that long to ENTER thailand on it and when you do you will get stamped in for 90 days (even if you entered the last day that visa was valid for), you could have applied months ago for the visa.
EMAIL them at this email and see what's what

Sorry that sounded harsher than I meant it, I did not mean any disrespect in my comment ๐
