We have had issues with Citylink too. We live on a busy road that gets very congested and they just dont want to come here and risk getting stuck in traffic.
So we are sitting here with the tracking info up online and it goes from stating that its out for delivery to 'card left, no one at home' and all the while we have been at home and didnt see a Citylink van pass the house let alone stop outside.
Obviously no card is left either and I always have to drive to their depot ten miles away and pick stuff up.
