[Resolved]  Flipkart — exchange mobile not picked up for unknown reason

Flipkart order id OD[protected]

I had ordered Honor 9 Lite (Midnight Black, 32 GB) on 19.04.19 with exchange offer for Lenovo K3 Note ( pictures attached).
Delivery person, around 18 years old & not at all serious in his duties, came on 20.04.19- 11AM without prior intimation when I was not at home. Anyways with great difficult my mother was able to hand over exchange phone to him, which he was least bother to check also & went off without collecting exchange phone & delivering my ordered phone.

Further when I contacted CUSTOMER CARE - Chaitra V Flipkart Customer Support told me to share the images which she will forward to seller and phone will be delivered.

After sharing pictures of old phone which absolutely has no dents/gaps etc., flipkart customer executive has called & told me that seller is not accepting the phone and asked me to cancel the order.

As I have phone physically with me, I don’t see any dents or gaps which seller is trying to say to not pick up the phone. Further delivery boy has no proof that phone is dent or damaged to verify against images shared by me.
I have only one question why is flipkart keeping such fraud sellers and why at all flipkart is keeping such exchange offers when flipkart doesn’t want to accept old phone just to waste customers time/money at the end.

I request flipkart to please arrange for seller/delivery boy acknowledgeable to check the phone & give the reason for rejecting the phone after physically verifying it.
I will not cancel the phone & if flipkart cancels delivery without proper verification of phone in my presence just based on photos without giving correct reason, I will escalate this issue at highest level. Escalation team also is not responding & just apologizing instead of taking up with the seller or wishmaster ( they call delivery boy – wishmaster  )

Expecting a reply at the earliest so that I can start using my new phone which is already delayed because of ## delivery agent kept by flipkart & fraud sellers who has taken my order.
