Game canal walk

i recently purchased a tv on the 20th of january 2024 in game canal walk an lg 65' smart tv the following day whilst watching the tv it switched off then switched back on i thought it was the software update continued to watch the tv and on monday didnt have that problem but yesterday the 23rd it switched off twice whilst i as at work and was advised off the problem i then suggested we take it back because if the problem persists we might be hold liable for the costs since we didnt inform the store please bear in mind i only had the tv for 2 full days upon taking the tv was told we need to send it to lg for an assessment and you have to wait for us to advice whether you will be refunded or get the tv back, how do you get a tv thats been opened for assessment thats only 2 days old its nolonger worthy its value and why do i have wait without a tv for an assessment that will take up to 21days after i just paid 11000 cash So the tv have the manufacturers defect how is that my fault? games policies are very bad and buying from them is the worst
