Flipkart - Package not delivered

I ordered safari * trolley bag set on *th aug **** priced **** and it was expected to deliver on *th aug **** but on *th aug delivery boy called me and said that he is unable to deliver today and package will be delivered tomorrow. I agreed with him. From *th to **th they did not contacted me on **th i called delivery boy he did not answer several time and after *pm he picked up call and said he cannot deliver my package. Next day same thing happened he said will deliver package on **th but early on **th Flipkart cancelled my order and processed refund..
On *th i complained to Flipkart about this delivery problem they said they will resolve it before ** aug on **th they changed date to **th on **th changed it to **th. No one is able to truly resolve my problem... They took my valuable time they have my money for * weeks now as the price is hiked one of their respective said you can order again... I want them to understand that time is real money and evaluation of my * weeks money keeping and evaluation of wasting my time on calls for problem resolution which was never solved but created new every time they talk.
