I am having a similar issue. My deposit was due today and I paid on the 29th. I haven't received an email confirming receipt of payment and when I emailed common law they told me to contact finance, and finance sent an auto-reply stating they try to reply within 3 business days. I have confirmation from my financial institution so I am hoping that is enough. I was also trying to check my uOttawa email address but don't honestly know how to log into that...do you have any idea when that information was, or will be forwarded? I also tried to check my "finance" page under uozone, but I don't have access to that yet either.
In the Facebook group there are 56 members in it however 12 of those are exec members from previous years. So according to the Facebook page there are 44 new students in it however there may be some who have not joined the group yet.
