Woolworths Killarney selling faulty cellphone

I bought a phone December 2023 the phone gave me problems within 2 weeks I took the phone back to the store they said it was software and they updated the software. January phone gave me the same problem they booked my phone and motherboard was replaced. February same problem the phone was booked again when I was phone to collect the phone they told me that vodacom said they can't pick up any error. I have been showing the manager videos that I take daily to proof that the phone is faulty. He said he will speak to Rap. I am stuck with the phone that is not working properly and Woolworths is not showing interest in assisting or to give me the new device. I have been awaiting for feedback to find out how is my matter being handled. It will be the 3rd time booking my phone with no solution. Honestly I am not getting a premium service at woolworths Killarney Mall. I wait for more than a week to get feedback sometime I take myself to the store just to find how how are they resolving my issue. It doesn't concern them that I stays days without a phone. Yet when I collect the phone its not fixed I still experience the same issue.
