Missed deadline for new account promo

So I opened a new chequing account with CIBC back in late may with the promise of $500 bonus and $100 Costco gc. I set up direct deposit at work but it took longer than 60 days, I thought I had 90 days to do it but unfortunately that wasn't the case. I also did the other required steps to get the bonus.

I called customer service but the rep told me unfortunately the bonus couldn't be applied because it was beyond the time frame and said he could try to escalate but from previous experience he wasn't able to get the bonus added.

I don't need the account and the only reason I opened it was for the bonus, is cibc so strict that they couldn't make an exception? It was only a couple weeks after the deadline.
