Claiming ITC under GST

Hi, if there are any CAs here, I’d really appreciate some help. I’m a sole proprietor providing services to foreign clients (export of services), so they don’t pay me any GST.

Over the past two years, I’ve bought several things for my business—like laptops, testing phones, furniture, etc.—and I’ve paid GST on all of them. The total GST paid on such purchases is around ₹2 lakhs.

Now, I asked my CA to help me claim a refund for this unused GST, but she says it's not possible unless I shut down my GST account. That doesn’t sound right to me.

When I looked online, I found that there’s a 2-year window to claim unutilized ITC (Input Tax Credit) by filing a refund application. Now I’m really confused.

If any CA can guide me, could you please explain the actual process? Thank you!
