Dear Roya,
I notice u r the only forum member that goes for " YES " under the Job Offer column, I'm not counting the member who applied before 4th May, although it took about 20 days more for him ( 2132 applicants are "him", aren't they?) than his contemporary applicants to receive PER. That is to say CIC verifies job offers comprehensively to make sure of the authenticity and it takes more time, so no need to panic, I'd say u re safe..
On the other hand if worse case scenario ur app would be returned u can always resend it as u don't need to be worried about the cap cup...
BTW I assume u r using a friend's or relative's credit card, have u told them to inform the bank that u re expecting a charge from CIC? I've heard members here suggest people to do that for extra safety margin..
