Ok, they - B/card, filed a defence, but they - the court, sent the AQ, not B/card. An AQ does what it says on the tin, it's for the judge to decide which track to put the claim on, how much time to allocate, etc... And the AQ would have been sent by your local court, not MCOL.
Sorry to harp on, but you say the court say "we have to wait for the judge to decide what to do". Regarding what? When you phone them, what are you asking them for? At the moment, as far as I can see, all you're waiting for is a court date. Aren't you?
If I may make some assumptions, the way I see it, is that everything is going according to plan: You file claim, they file defense, AQs get sent out and returned, court date gets set, etc...
Ahhh, unless B/card didn't return THEIR AQ? In which case, judge would have to decide whether to throw their claim out and award you judgment by default, or grant them more time to comply...
Ok, 1st things 1st, we need to know where you stand. So ask the court office:
a) whether B/card returned the AQ or not.
b) If not, whether judge will allow you to apply for default judgment.
c) If yes, whether there's any update on a court date
Let us know how you get on.
