Ekart Logistics — Pincode-Address mismatch

I have given correct address but the delivery status shows as Pincode- Address mismatch. I spoke to Customer service rep. and gave him the correct address once again but still no response, they keep on saying the item will be delivered in next 1 hour, but it has been 3 days and i haven't received my parcel yet.
Please look into the matter and do the needful. I will be thankful to your quick response.
thanking you,
Roshan Kullu
