Upgraded fiber, disconnected in error, now no internet at all

Our line was upgraded by supersonic last week, to be activated on 1dec. It's the 6th, and we were disconnected instead of upgraded by vumatel. We now have no connectivity, supersonic is blaming vumatel, and vumatel stop responding...supersonic just say it's escalated, and logged with vumatel, and we have to wait for a reply from vumatel...
