Truecomretail — Order is delayed

I have ordered an item from Flipkart and the courier partner was TrueComRetail on the 6th of June which was supposed to be delivered on the day12th of June. They have not delivered and told due to unforeseen reason order was delayed. Later it was rescheduled to June 14th which is yesterday and even I did not get any notifications so far or status have changed. This is one of the worst experiences in Flipkart with this seller especially. This kind of act will spoil big company names like Flipkart. I hope they take necessary action on this as mine was not the first case to do so. I am waiting still to deliver the product.
