OnePlus India — Re: replacement of full new tv or refund

On 23aug2023 I was facing multiple problems with it for example display problem and remote not working so technician visited and he informed me that 3 parts will be replace (mainbord, subbord, display) and I am facing this problem within an year of purchase.almost their replacing 90% parts of my tv only10% parts aren't replacing(power cord cable and speakers are the only parts which are not replacing) and finally on 31aug2023 technician came with display and he changed it but mainbord and subbord was remaining but they have marked my service as completed and after 10days I was facing same issue and again they inform me that they will replace display again and some other parts like mainbord and remote. So I have requested them to pls provide replacement of full tv or refund and already 39days have been pass but till now I have not received any solution from their higher authorities and I have sent n number of time Mails but I have not received an single response from OnePlus And This meant that It made me feel frustrated and mental harassment, always providing fake promises and incorrect information
