Battery repair of a Samsung S22

I went to a Samsung repair centre 14.05.2025 as my phone battery was swollen and i understand it was my fault and i needed to fix the battery and i paid for it to be repair. The 10.10.2025 i when to the same repair centre and told them that this device keeps restarting and i said it have a error about major software issues detected and she the device is out of warranty i paid again the Labour fee of R399 and they did n software update on the device and said its right now. Ok I just came home and the phone starts to restarts again. I called told them about the issue, again i need to go back Samsung repair Centre . I when on 27.10.2025. They did a assessment again and told me my battery need to be replace again after 5 months. I told them the battery was replaced 5 months ago and i was told i only get 3 months warranty on the job than. I told them the battery the sold me 14.05.2025 could have been faulty and they have to fix it as they did the job the first time but they are refusing to, and said i need to pay again so i when to know, does Samsung SA think this is right. Job number 14.05.25 is 44412, 10.10.25 it was 50526 and the last job was 51110. Am i wrong to feel the job they have to do out of there pocket since a bad job was done 14.05.2025.
