Poor quality Defy

Purchased a defy fridge in 2018. Had to repair it twice for the same reason which makes me believe that the product itself was a problem.

In 2019 we noticed that the fridge stopped cooling we called the customer service line and they managed to get the fridge repaired.

Again in 2020 we had the same issue and they sent out a technician to repair the fridge. I am not sure what the warranty period is but surely the same issue can't be occurring now the 3rd time.

I would like some assistance as this is a reputable brand that many households trust.
