1) Product was delivered on November 5 (it was supposed to be delivered on November 3 but the recipient had already left the house because he was in town for Diwali and so didn't want it). Your courier partner, Jatish Kamat ([protected]), marked the package as delivered online but never actually handed it over. He later requested us to accept it and return it because he only gets paid a few rupees per delivery, we immediately request the return of the product on your courier boy's mistake and request.
2) On November 7th, I bought more stuff, which was delivered, however the delivery man took all the return product back with him. We didn't even attempt to open the cartoon's box; it was still tightly sealed.
courier partner took the package back after opening it and checking that all 11 things were in it.
3) I checked my account after a month and saw that it still needed to be picked up, thus I realized I still hadn't received my money back.
I tried to get the courier boy's phone number from the call log and sent an email to Decathlon.
4) courier partner boy Jatish Kamat ([protected]), who returned all the goods on December 23rd, kept them all for aroudn two month, with one item missing ( Adult cable-knit wool ski hat grey) cap

courier boy signed a paper to the fact that he has only delivered ten items, one item missing ( I believe courier partner lost it somewhere). We can send a picture of ten items ( one item missing) that your cos. urier partner gave u

We never opened a package, or removed any tag from a product.
this is going on from last two month and this issue and irrelevant issue has cause two much pain and time loss and my effort I would like to return the product and get my money back.
decathlon should take action against courier partner and compensate me and my family for this.
