Premium tv big problems

I bought a qn**** I have had issues with earc remote loosing connection screen going off and on frame rate issues and it’s only 1 week old Samsung now want to come to my house and mess my time around to come view tv I work 7 days a week the tv is literally brand new I want a refund or another model, I can’t have a tv that costs so much doing what it’s doing in the first week it’s already been 4 days since contacting Samsung and nothing has been done they must forget if they think I’m going to make time for them to go and sort out their sub par tv I expect feedback soon

I have owned many Samsung items but the way they have treated me this time makes me feel like moving to lg better service and better products
