Samsung A05s is a load of ****

I purchased my Samsung A05s from Game Pavilion about 2 months ago, 13 March 2024, and I started experiencing issues with after 2 weeks of collecting it. My online purchase from Game was very easy and satisfying and I was very excited to get my brand new phone. I had done extensive research online for affordable and reliable phones and I had a choice between Samsung and Xiaomi but I opted for the more 'trusted and reputable' Samsung brand which I regret now. After 2 weeks I started experiencing intermittent issues with the touch screen which I didn't pay much attention to but the lady I contacted at Game Pavilion said I could not get a refund or exchange, I have to take it to their technician who will assess it. I didn't appreciate the inconvenience of not having a phone while waiting for the repair. Firstly it's a brand new phone , why should it be repaired??? Secondly it only lasted 2 weeks of satisfactory usage. Thirdly, I rely extensively on my phone daily for work. Being without a phone was not an option, so I grudgingly decided to keep the phone hoping the touch screen issue might magically resolve itself just like it magically started after 2 weeks. With regret, the issue is now constant and extremely annoying which is affecting my work. Every time I unlock the phone the screen goes bonkers like there is a ghost in there opening apps, or typing random text and it even called my sister once. Every time I have to unlock, then lock it, and unlock it again for it work 'properly' for only a few minutes then it goes faulty again. I have to do this repeatedly every single time which is EXTREMELY FRUSTRATING to say the least.
