Appalling Service from Samsung

On the 8th of February, I arranged for a Samsung technician to look at my boss’s faulty TV. He couldn’t fix the TV on-site so he took it away to the Samsung workshop for repairs. Two weeks later my boss’s TV has still not been repaired. We have called on numerous occasions and each time we are told that they need more time to find the problem. Today, the 21st of February, I called four times. At one point I waited for 30 minutes to speak to a supervisor, but all she could offer was to ask us to give them yet another day and that she would also escalate the issue to a manager. I asked if I could speak to the manager, and she said that was not possible. To summarise, two weeks after Samsung picked the TV up, nothing has been done, no one seems to be able to repair it and there is no mention of swapping it out for a new one. I have also tried to call the technician on his mobile, but he won't answer or call me back. My boss was also told an email had been sent to us, but none of us have received this email. I told them if I did not get a response by 10h00 today I was going to report them to Hello Peter, then I gave them until 11h00, then until 11h30 and at 12h30 I decided to report them. Samsung obviously doesn’t mind being reported for bad service. Samsung is supposed to be a well-known and expensive brand, but with this type of after-service, I would rather go for another brand in future.
