Samsung — Please approve return of my cancelled order which has been delivered to me by cheating

I have cancelled my order with Bajaj market worth Rs 21999 and ordered new phone from Samsung shop worth Rs 23999. They have sent me the cancelled order which I thought has been sent by Samsung Shop and received it (since the outer cover of mobile box, date of delivery and delivery service company were almost same). After then when I realized that I have received the cancelled product worth(rs21999), I connected to Bajaj and they told that they will take the return and asked me not to even open the delivery packet and I did the same. The next day my original order( worth rs 23999) from Samsung shop also arrived. I received this order as I was promised by Bajaj that they will take return of cancelled product. But after few days they took a U turn and said the dealer( Savex technologies) is not ready to take the return and I have to contact SAVEX. When I contacted SAVEX they said that I have to contact Bajaj and they didn't listen even a word. In this blame game between SAVEX and BAJAJ, I have been trapped.
At the end, I would like to request Samsung and SAVEX TECHNOLOGIES to kindly approve return of the product worth 21999 since I have cancelled the order before delivery and have also purchased a new mobile worth 23999 from SAVEX only. The product is lying fully packed and unopened with me from last few days. I hope that Savex technologies will consider the genuine request of their customer and understand my situation. I have already bought a Mobile worth 23999 from you SAVEX TECHNOLOGIES and I am your current customer. How will I be able to pay loan of the product which I have cancelled. So please SAVEX TECHNOLOGIES approve the return. If you are concerned about the situation of product, then you can send your inspection team too but take back your product as a Goodwill gesture atleast. I won't be able to pay EMI of 2 mobiles ( for the product which I have cancelled. I hope you will understand my problem and approve the return.
