As I understand that, "finished with Ajijic", I think it means that they have installed that infrastructure. It would not mean that all installations are finished.
If you are not at home when Ilox calls, perhaps more than once, what do you expect them to do? They will 'move on' in order to keep their installers busy, and you will drop down on the list, or even be relegated to a 'maybe they died' list.
If you were a merchang, holding an order for a customer, how often would you try to contact them to come and pick it up? Eventually, you would put it back on the shelf.
