Ecom Express — Delay in deliveries EcomExpressNCP/[protected]

I was following this shipment since it reached Kochi hub on 23rd. It took another week to reach Cherthala DC which is hardly 30 km away on 30 August.. Since then I am following Ecom express for delivery. No proper reply except "we have some interal issues". They keep on changing delivery promising date. They promised Sep1 and then 2 and today they shifetd to Sep 4..One of my earlier order was returned to supplier due to same reason( AWB[protected]) and they could not deliver even after 7 days from committed delivery date.
