Yes, I applied for SC and OCI. I had looked for OCI appointment and found one (I didn't know about the hack or the time when I saw an opening) within 1 week. But the issue was I didn't get any email confirmation. They check for the confirmation at the front desk and at the security. I explained the situation to the front desk, I said the same thing to the security but since my name was not on the list, he said I can not get in for OCI. So, I got in line for SC. Front desk checked my name in their computer (I think so when I said about OCI). I don't know if they saw my name there or not.thanks @funloving for the details. so, since u are based out of Vancouver, did u apply for both SC +OCI together because I see in a later post that you have already got ur SC. And for booking appointments at Surrey , based on a previous post from @vvarma,there are new slots open between 7-7.30pm PST every day, I am hoping to get an appointment during this window.
Hope this helps.
