I'll advise you go for your certification for 2 reasons:
1. Getting an Internationally accepted Certification like Cisco gives you more edge than any PGD.
2. You'll still need the certification even after your PGD.
However, you'll need to consider some other personal factors like Finance before you take your decision. In addition, you need to be clear on what exactly you want to do i.e. If you intend to build a career in IT or not. I hope this helps.
