Flipkart — Customer care service and delivery service

I have ordered a washing machine from flipkart. It has reached to nearest delivery hub on 16th Jul'22. It was supposed to be delivered by 19th Jul'22. Today, it is 26th July, still it is not delivered. Delivery time kept on delaying due to unspecified reason. Flipkart customer care is giving automated replies to my queries. No contact number is available to call flipkart or delivery agent. The call back facility is also not working on flipkart app. Now, I am at mercy of this irresponsible organization
