Delhivery — Refund not done by the company

I order an Laptop Delivery Via Delhivery Courier Service. For this i paid extra amount for safe keeping the package and Express Delivery as i needed to move it urgent . While pickup i told the pickup person, its a Laptop and they did not raise any concern and picked it up, but they cancelled it after it reaches their center raising concern its an Screen object . The Package was there for 3 days with no not notice of when it will be returned. I called the Delivery Center in my city and they recommend to cancel it for early return. I cancel it so it reaches me ASAP and i can arrange another courier and it came to me on 4th day . Delhivery team did not refund my money, i sent around 3-4 complaint emails but all absconded. Please help .
