Vijay Sales — selling defective samsung refrigerator

Address:

Vijay Sales, Mumbai

I purchased the samsung refrigerator rr20r182zut pebble blue on aug 21, 2019, and have been experiencing cooling issues since the first month.
We have raised issues with samsung and vijay sales and get nothing except emails from them (Samsung).
A service engineer is sent who always informs he is at a certain location and will arrive the following day or later but fails to keep his commitment. Although i do not have any issues with him visiting any hour as my parents are always available due to their old age.
The one time he did actually visit he mentioned to my parents that the refrigerator is not working as intended as the light bulb is faulty and due to which the entire system stops (I want to believe this but..). He then goes on to replace the bulb and leaves for the day. The cooling does not resume; although it's not dark now when we go looking for the items stored in the fridge. Hence, would like to thank the engineer here!
After months of chasing them as they now have an awesome reason (Read covid-19 here) to delay everything has led to us completing one year with this defective fridge. I'm not sure about the extended warranty or anything as nothing has been conveyed to us.
@vijay sales: my parents being the old couple that they are put a lot of faith in your stores rather than making an online purchase through the various e-commerce portals available at the tip of our fingers. I never intended for them to go through so much hassle to just store their food! Given the current situation of covid and the impact that it has on older people, i expect nothing more than them being safe and use the fridge for which i've spent my hard-earned money (Rs. 13600 to be exact).
@samsung: please do not just forward our emails to @vijaysales as we can do the same. We reach out to you because we have already reached out to them.
My request is for having a full refund of the product or a brand new product in return as we have already witnessed the great level of expertise and knowledge of the engineer been sent to us.
