breach of contract and negligence

Hello Peter, I bought a phone at Edgars store and they told me it was under insurance for 3 months with 3g mobiles, a month after purchasing the phone I took it in for repairs, from the 30th of May 2022 till the 10th September my phone has been with them. when I enquire, I'm given different stories. 1, the IME No on my phone does not match the IME No on the box. 2, my phone has not been delivered to the repair center. 3 my phone was fixed and sent back but delivered at the wrong store. today 16th September nearly four (4) months now I am told that I have to pay R2000 for my phone to be repaired. all along my phone was not fixed.
