Delhivery — Replacement QC failed

Address: Mohalla Kalyan Singh, Mill Road, Mawana 250401

Hello, I ordered Nike Shoes size 8 from Ajio on 4th august with the order Id:- FL[protected] and I received the product on 9th of august. When I tried the shoes on they were feeling a bit tight so I placed an exchange order for a plus size. I received my exchange order today and the delivery executive took back the original size 8 order. After 5 hours, I received a call from delivery executive saying he will have to pick up the exchange order and give me back the original order. I was confused and asked him the reason and he told me that EAN is mismatched. I called ajio customer service for the issue and made them talk to the delivery executive and Ajio team itself confirmed that Ean is not mismatched and there is no need to take back the order but the delivery executive was rude and he cut the call from my phone and took back the order. I followed him to the delhivery office and they were very skeptical giving me fake excuses and they told me I have to file another return but I am not getting the option to return the product and I am stuck with size 8 shoes. Also when I returned the size 8 order the box was in good condition but when he gave me back it was all broken. Please help me
