Samsung - internal defect of refrigerator freezer and customer care is not supportive to resolve

Here is a brief summary of my case:

On **th February, I raised a service request (**********)regarding my refrigerator with Samsung customer care, which was purchased in September ****.
On **th February, a service engineer visited my home and confirmed that it was a design defect (internal) that could not be repaired. He mentioned that a customer care representative would call and explain the further process.
On **st February, I received a call from Samsung customer care, and they mentioned the amount, etc. I expressed my dissatisfaction and asked for a breakdown of the depreciation, etc. The representative said they would call back but did not.
On **nd February, I called and inquired. The representative mentioned that they had requested some information from the distributor and were waiting for a response. They said they might get back to me by Tuesday.
I did not receive any call until Thursday (**th February). When I called and inquired, they mentioned it was taking time and might take another * or * days.
On *st March, they mentioned that I should speak with the distributor to expedite the process. I spoke to GIRIAS accordingly.
On *th March, I called again and received the same response, saying that they had not received any response from the distributor and that I should call and ask. I spoke to GIRIAS again, and they mentioned they were sharing the information.
On *th March (today), I received a call from the customer care representative, who said they could not proceed as they were not getting a response. I asked what that meant, and they said they could not proceed. I asked to speak to a higher authority, and they directed me to the centralized customer care. I called the centralized customer care and explained the whole scenario. The representative could not give an answer about how long I should wait and whether there were any timelines for the closure of the request. I asked to speak to a higher authority, and I was forwarded to the service officer/escalation manager. She listened to everything and said she would connect with the local Samsung care person to get the details, which she did. After the discussion, she mentioned that they could not do anything unless I have to go to GIRIAS store and get a revised invoice/letter. She also mentioned that if I did not get the revised invoice, they would close the request by tomorrow.

Apart from speaking to customer care, I've dropped email to Samsung head where they said please provide invoice which and didn't care for customers. Also I tried to reach ceo India also no use,.
So I'm approaching here
