Panind — refund of my payment

Address:

VILLAGE SUNHI, V. P. O SUNHI, 176037

I applied for a pan card and i didn't submitted my documents, but i paid 499 rupees but my application wasn't completed. Then i came to know that i could get my pan card at 110 rupees, so i email panind for the cancellation and refund. They said we get to you in 3-4 days, but they didn't reply, so i feel cheated. I want refund of my payment. Thank you.
