Samsung Customer Service

This is now my second email to Hellopeter. I've been having endless problems with my Samsung Galaxy A53 5G which I took a contract by the Telkon store in Adderley Street Cape Town on the 8th April 2022. I've used it till August 2022 and been having issues with this handset. It's been to the Samsung technicians in Johannesburg 3 times already. They send it back saying there's nothing wrong with it. I then sent it to the Samsung store in the Waterfront in Cape Town and they then forwarded the phone to some repair store in Bellville Cape Town. My phone was there almost a month. I had to pay for the courier to Cape Town and back to Potchefstroom. I received my phone on 7th November 2022. I've been using it but still has issues. I called Samsung Customer care on 8th Nov 2022 spoke to Michael and explained my problem. He then said he would forward it to the relevant department. No one did a follow-up. I called them again today 11th Nov 2022 and spoke to a lady in the Customer care department. I then asked her to get a manager to me back. I would not complain about my handset if there was no issues with it. I have other Samsung handsets which I've had no problems with. This is my first experience. My call ended because I had no airtime left. And no one has the decency to call back when they have all my details on my profile. It's really frustrating and very disappointing as to how I've been treated by Samsung. I would like this matter resolved or my phone to be replaced with another brand of phone, and my account to be credited so I can get another handset. At the end of the day I'm the loosing out as my handset is being paid to Telkom but I don't have the privilege of using it. I would like to advise anyone to think before purchasing a Samsung cell phone because their after service is disgusting.
