Lack of service at Cell C repairs centre

I took out a contract at the end of October 2022 for a Samsung A73 being assured by the sales person (Aubrey) at Cell C Clearwater that it was a great phone. I was told that the device had a warranty but not on screen or water damage. On 4 March my phone stopped charging and would only charge on "slow mode". I took it into Cell C clearwater on 5 March in PERFECT condition, in its original box with a screen protector on. I hear absolutely nothing from anyone at Cell C and then receive an SMS on 27 March stating that I need to either accept or reject a quote with no quote attached. After 4 calls to the repairs department I finally receive a quote of over R8100 for a phone worth R9999 which is under warranty. When I ask the manager (Nkosikona) why I am receiving a quote for a phone that's under warranty he says that the phone was physically damaged. He also never returns call or gives feedback. On another call I was told I burnt it. I delivered a perfect, Immaculate phone to Cell C with NO damage to it. I then visited the Cell C store at Clearwater after spending 2 hours on the phone to the repairs department again. The consultant showed me all of the comments on the phones condition and it seems that between 5 March and 8 March suddenly the phone is scratched and dented. Nobody wants to deal with me or be accountable. On 5 April I receive an SMS that my phone has been received back from the repair center. I AGAIN phone the repair center on 11 April and I'm now told that my phone has now been sent to the Samsung repair centre and I need to be patient, again. They have had my phone for over a month with NO progress or answers. This is simply unacceptable for a phone that's virtually brand new.
