Delivery Expected by Oct 12, 2021, And these 4 items were delivered in a single packaging on Oct 26, 2021, (Delhivery AWB[protected] after long follow-up with Flipkart and courier partner. When I opened the package on same day, I found all the Four cashew boxes seal was broken, Even two Cashews boxes was half empty. Luckily I have made the video of the unboxing as well. There was no return option showing for this order, so I immediately called Flipkart CS on 26th Oct and the CS agent initiated return for this items, only for two boxes, not for all 4. (I don't now why). Return request has been accpeted with Return ID[protected].
