NEW AGAIN WILL I BUY ANYTHING FROM THIS STORE!!!

Good day Two years ago I bought a Hisense sound bar in August 2022, It stopped working December 2022 and I returned it. In I think April 2023, I received a new one, different brand (sinotech) because the Hisense could not be fixed. Just last week it did the same the Hisense did and stopped working. With the warranty being finish please tell me what I must do because this is the third product I bought from Hi fi corp that’s giving me issues. First it was the tv box and now the second sound bar. Well the reason I am writing this is because i am starting to question your products ? Well concerned because people always say that the products you sell always have faults and yet now im convinced right!!! My mom bought a sound bar same time as mine 2022 from Game and its still working perfectly fine compared to me being on my second one it’s actually very sad that I am experiencing this with Hi Fi corp with all products bought from you in less than a year. can you look into this matter and provide feedback asap. I still have my receipt I have received for the SECOND SOUND BAG. You are, therefore, earnestly requested to replace the sound bar. The manager of Southgate called me and told me that i should pay R450 for them to take it in for repairs and if they can repair it will i have to pay and if not will i forfeit my money... AFTER TWO SOUND BAR'S at the same store.. i will never in my life ever buy from you neither will i refer anyone.... third item that's giving me issues and HifiCorp is just unsympathetic!!!!! my friend bought her sound bar same day with mine at Game and she is still using it , no issues at.. your products is questionably
