Uncapped Suspended

My network has been suspended for what reason I have no idea since my adsl is uncapped. For 2 days now I have tried phoning the call centre and have been told we are experiencing high call volumes out of the 6 phone calls I made, 3 of those calls was on hold for over a hour each and spoke to no one I still haven't spoke to anyone. I got an uncapped adsl for the purpose of never being cut off.
