Flipkart — Whirlpool refrigerator bottom mount 355 lts

I am totally dissatisfied with the product and service. I need a replacement with either another brand or I would request you to cancel and provide me a refund.
Firstly, the delivery agent rejected my LG refrigerator (which is in a good condition ) for exchange and asked me to pay 7000 Rs to get the new Fridge. He refused to take it for the fact that it has a very minor dent. I agreed to pay since I had no choice.
When I unboxed the product, I noticed it has limited storage capacity and moreover it has coils visible at the rear side of the frigde.
It makes no sense paying so much (close to 40K) and getting limited storage capacity fridge and having coils visible .
I called support numerous times and requested to speak to a Supervisor/ Manager, but the support agents disconnected the call after putting me on hold (almost three times)
I need a call back from a Supervisor/ Manger to discuss this issue and see how this can be resolved or provide me a better solution.
Because neither me nor my family members are satisfied with the product and I cannot live with it for the rest of my life.
This product is still in UNUSED status along with the all the packing.
I am ready to bare the transportation charges if required.
Expecting a call back from you at the earliest.
