Spice Jet Airlines — Inordinate delay in getting refund

Address:

B 1901 Marina Enclave , Jankalyan Nagar Malad West Mumbai 400095

This refers to PNR LDER4Q.
Against above PNR spice jet confimed on 14th April that the refund is due and that they will disburse refund on my Bank Account.
Certain documents as far as name, account details were given as requeted by Spice Jet.
I regularly contact the customer care and they say that I will get the payment in 2 days. This is happening again and again.
The amount involved is small and I fail to understand why the refund team is delaying.
Just 2 days back, I sent a copy of my passbook statement confirming that no money is yet received in my account.
Request your intervention please.
Thanks
