Flipkart — Cheating Name of Smart Upgrade

.Hello Flipkart,

I bought  realme Gt  master on 15/12/2021(Order ID - OD[protected] under Smart Upgrade plan
 Rs. 7800 amount needed to pay one year later or return my mobile to Flipkart while upgrading mobile. So I returned my mobile under the buy back option (Order id-OD[protected] on 14th December, 2022) but pay later bill got generated along with 7800 Rs. So I need to return my mobile at zero cost and also need to pay a smart upgrade amount?  Are you playing with me? Why should I want to pay ? Even after returning my mobile to Flipkart? Raised complaint on January 1st, 2023 almost 4 months are gone. The complaint keeps on escalating every day I will get the call from flipkart they will tell me it is under process please wait for 48 hours or 24 hours etc... Next, send your account details we will send to your account but still I did not receive and next we will transfer to your gift voucher. I also agreed that I did not get any voucher from flipkart. so final conclusion is I lost my mobile and money flipkart is cheated me, I will sue you in court and claim extra money for testing my patience, wasting  my time, trust etc.

Regards
Vivek.s
