Samsung — Refrigerator service

My samsung fridge stopped working last year . I registered my complaint on toll free number of samsung service center. Next i got one mssg with the details of local service provider.
Later in the afternoon he came and replaced old damaged compressor with a new one of different company (LG) . He charges 5000 rupees and took the receipt with himself only. Now in 2020 my fridge again stoped working and when again called service center they told me there no record of my previous complaint as my warranty period is going on. There service provider is also not recognising my complaint. they have cheated me and now they are asking money for compressor again.
