Eircom Broadband - HELP!

ok, Ordered eircom broadband online on Jan 12th. Printed off order confirmation etc.
Rang today as no modem has arrived yet. Was basically told they the sales people don't really know much about the online ordering but that the girl I spoke to had no sign of any order from it and that it was basically tough. She then went on to tell me there were now no free ports in the exchange and that again it was my own tough.

The confirmed order it seems counts for nothing. You can imagine that things got a little heated around now. So where do I stand? Considering that my line passed the check and that the online ordering system allowed me to confirm my order on Jan 12 i assume its safe to conclude that back then there were free ports. But they messed up. So how long does it take for new ports to be created in an exchange?

Second, when I asked her when exactly did eircom intend to let me know about this she had no answer for me. So it seems that they had no intention of letting me know, again despite the fact that I have a confirmed order printed off next to me.
