Bad customer service

I bought a Samsung A12 in October 2021 from the Cape Gate branch. In Feb 2022 not even a full 4 months later the screen went black and white. I reset and re checked all settings but nothing brought the color back. I took it back to Makro as I bought it there NOT at vodacom. I was told they have to book it in for assessment. I explain there already that I do not want a repaired phone back as it should atheist last for a year before giving problems. The lady that helped me said that after it comes back I can ask for my money back if it's not a software problem as that is not under guarantee. It clearly is a hardware problem. I let everything go as per their procedure. Today I went back as the device is back in the store REPAIRED. I was polite and asked my money back but from the sales person to the merchant manager they had excuses. On the invoice they give you when they take your product number 3. It states that you can request your money back. The phone is booked in again cause they must ask Vodacom now if they will refund me? Did I buy the phone from Vodacom or Makro? Why must a person always have to fight and be rude to get results? Vodacom is the 3rd party, Makro is supposed to sort out the problem. Now I must wait another 24 to 48 hrs to get answers. It's my right as a consumer to get my money back as the product I'd faulty by no fault of mine.
