Dear wizz, listen well: it's absurd that the admin of a service like yours for days and days not showing signs of life and let his service is not working as it should. I understand the holiday season, but or close together for a few days, or if the service is open it must work at 100%. This suggests that wizzupload is an amateur service with the final logical consequences (R.I.P.). The January 10 is approaching and that day will prove if all your claims are true or just words.
....the problems aren't only for upload... some files suddenly can no longer download.
