Hi @Toddy94 Sorry you have not had a great experience, certainly some customers have issues but this is not universal. I have had Samsung TV's which have lasted a considerable period of time though that may not be a help to you.
However as mentioned the first port of call is with the retailer , after 30 days the retailer must repair or replace and if repair is unsuccessful consumer entitled to a refund. Rights against the retailer can last up to 6 years, however after 6 months the onus is more on the consumer to prove there was a known issue at the time of purchase.
I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.
My Device- S21 Ultra 5G ( SM-998B/DS ) CSC= BTU , 12GB/256GB
