Samsung Refrigerator Replacement Issue

My Samsung refrigerator broke down, and they promised to perform a service, including an examination of the product and a paid replacement. They removed the product model number from the service and stated that the item would be returned for this amount of money. My refrigerator, RT47CB66328A, arrived after more than 20 days, and they told me the fridge sent from the service would arrive soon. Instead, I received RT47CG6002S9 with no explanation, which perplexed me. Bringing a product without any communication seems like a mistake, and I'm curious what the Consumer Rights Committee thinks about it. I'll be contacting Consumer Rights for assistance. I need my problem resolved as soon as possible.
