Flipkart — Non delivery of the product but showing delivered

Dear sir, I have ordered Luminous Inverter battery 150 AH in flipkart on 7th OCT 2021 with order id:OD[protected] which is a prepaid order. And on 7th Oct there is no tracking ID but showing the product is shipped even till 20th Oct. The screen shot of the same has been saved then for future.As i have belief on flipkart that the product will any how be delivered on 23rd oct as in image attached or may get delayed. But on 23rd night its updated that the product is delivered on 14th oct itself . THis is ridiculous that updating on 23rd oct that the product is delivered in 14 oct. I had raised the issue on flipkart on 24th oct. The complaint has been forwaded to the concerned team by the customer care executive and its been told that the issue will be solved by 28th oct. But i didnot receive any call regarding this till 28th oct and on night they have updated that the issue will be solved by tommorrow. Yesterday also the issue is not solved. When i request a call back by raising the complaint they are just telling the team is working on it. But the team never called me and gave any update.

So i request either to deliver the product or refund the amount as soon as possible
