Samsung The Worst service on their flag Ship Product S23 ultra

Bad Service ; Worst Service I received a new Samsung s23 ultra 5g on my Vodacom contract. from day 1 I had issues with the phone (no sound, incoming call on silent, when recording a video it says u on a call, and and....) took the phone to Samsung Clearwater Mall within the 7 days the customer care lady did a soft reset and said it should be fine. still faulty. went back spoke to a technician who said he needs to do an OS reinstall. he charged me R450 for the backup. made me sit there 3hrs then Winston the technician came back to me and said their internet is not working I should come back. Came back the next day for the OS installation, waited another 2hrs. then came back the 4thtime still not working. and here the shocker this head technician said to me I should take it to Eastgate center because he would be bias and i should get a second opinion. asked what he means. he said Samsung won't replace the phone because the fault is intermittent, he eyes. store manager Gerome had the intervene and booked the cell. the technician said he will call me in an hour which never happened. I called him this morning, and this was his response. he ran Dianostics on the cell and he thing it will be fine. and I can collect it after lunch. This has been the worst service I have received from an international company who claims the give u the best customer experience. I reported this to the head office and the response is we are escalating it to someone.
