Videocon n Electrolux faulty fridge, beware

I bought a NO FROST Electrolux fridge from Vijay sales Borivali and one week into its usage the fridge started accumulating ice in the freezer compartment roof n sides, after many calls and many visits from the technicians of Service Delight( the repair centre that services the Videocon range) the fridge was taken for repairs.
The problem still persisted, the technicians are telling me that the ICE in the NO FROST freezer compartment is NORMAL????

I fail to see how this is normal. I have used a NO FROST fridge for 20 years prior to purchasing this one so I am aware of how a no frost fridge functions.

I have emailed /posted pics of the ice inside the freezer roof n sides to the company, no response.
I have asked that they either refund my money or replace my fridge free of cost.
Their response is awaited.
