Query about refridgerator part unavailability

Dear Experts, In 2009 we purchased a refridgerator from Samsung. 3 Weeks ago, my fridge stopped cooling. Samsung technichians informed me that the problem is in PCB and the company has stopped manufacture of products of the model. I was advised to purchase a new fridge as a solution for my complaint. Im facing a problem in the absence of the fridge and theres no response from Samsung. I always purchase Samsung products.After this experience decide not to go for it. A company usually makes the spare parts available till 15 years. I want Samsung to compensate me for the product with its market value. Please advice how to proceed. Please help with your advice, experts. Rgds, Zoya.
