Samsung.. i need to be heard

On 6 September 2023 i posted on here about my constant struggle to get the help i need with my Samsung washing machine..Dealing with Samsung, Makro(where i purchased the washing machine) & the 2 service centre's & their *********** technicians that Samsung had sent to me. I got a call from Samsung last week after my review & was told they are escalating the matter & will let me know after speaking to the necessary people & reviewing all the information regarding my repairs what is the outcome.. Today i got a call stating that according to the technicians of Circle seven my unit is repaired & it's my uneven floor that's the issue. I told the lady Tiffany from Samsung that is not the case & she told me to hold while she connects to the technicians of Circle seven so they can tell me what they told her, the 3 way call questioned my character & values as it labelled me as a **** cause these technicians were lying & the customer service agent believed them & told me that she is closing this case.. i had to beg for her to let me prove I'm not the **** but they are cause if she closed the complaint then according to her i have to wait 3 months before another service centre can be sent out to me to check the fault that hasn't been repaired since April 2023. I kept on telling her they are lying & i kept asking them why they are lying but all i got was "there's nothing more we can do"..they sent her a 5sec video as proof that it was repaired & she believed them yet I'm telling her over & over again it's not but i was disregarded to the point where i almost believed i was wrong but i wasn't. I did everything exactly how those technicians wanted with a 100% level surface since they were blaming the uneven surface & placed the washing machine where they had it when they sent her the video & i sent her a video from start to end with every step of the process to prove to her i wasn't lying as my video clearly show it's the same as before with the same fault.. it took my +-14min video for her to see that I'm not lying & book another sevice centre to come & check the unit once again.. is this customer service Samsung?? Is this how i should expect to be treated by Samsung going forward?? Will i need to beg to be heard?? Will you question my character & values everytime by believing I'm a ****?? I deserve to be treated fairly.. i deserve to get help cause i paid for this washing machine with my own money that i worked hard for.. i deserve an apology for having to beg for help.. i deserve to be heard..
