No Samsung!..... this is not good enough!

During middle December 2019 I bought a brand new refrigerator form Samsung. It was only delivered middle January 2020 - so we started to use this spic and span new refrigerator during January 2020. Within the first 24 months, this appliance broke down on 5 different occasions. During November 2020 I had a conversation with somebody at Samsung (telephonic). I requested that Samsung must exchange this appliance as it is certainly not normal for a refrigerator which is in use in a normal household, and bye-the-way, did cost me R40 000, to have 5 break-downs in such a short period. I was informed that the matter will be investigated. Until today I have not received any feedback. About three weeks back the refrigerator once again gave me problems. I informed Samsung. The only response I received was a text message and that was the last I heard of them. Is this the quality of client service which Samsung want to be known for?
