Samsung sucks

I've been calling for 2 weeks trying to get someone to come and check or repair a washing machine that we purchased in Dec 2019. Samsung calls and says the service center will call and the service centre calls and says if we open your machine your warranty will fall away. When we call Samsung to ask about this we get told someone else will call us and days go by and no calls. Today I get a call to rate the service like really the work hasn't been done so I go through the whole process again of explaining and guess what she says "I will get someone to call you" ..I only have Samsung appliances in my home and now I'm regretting having so much faith in this brand. WHAT and HOW on earth do we get this sorted as it's over 2 weeks now!! We cannot call a general person to fix it as we lose our warranty but Samsung calls and says if they come themselves we could lose our warranty. They also say themselves that it sounds like a motor issue but at the same time if they come out themselves we lose the warranty. How does that make sense?! How is that fair?!
