Still waiting

We upgraded our line to the 10mb with explora, thursday will be 3 weeks from upgrade. Last week after numerous complaints we finally had someone fix and upgrade our line. Phoning daily to track the explora delivery, no one knows when. Either they say the order hasnt been placed yet, or they dont know when the order will be placed or when we will receive the explora. How can you advertise something you cant supply??? Can someone contact us regarding this matter plz!!!!
