I am paying for devices I have not received.

I bought an iPhone around May and a laptop around October 2023 at Foschini. In November 2023 I lost my iPhone while travelling and my phone was insured, I immediately reported this at the police station and submitted my documents at Foschini to claim for a new phone, while I was busy with that I realised that my laptop was faulty, my laptop was not connecting to the WiFi and I would freeze for hours. I complained about this matter and they asked me to hand it over as they will give me a replacement.

I kept on following up about the devices and they keep telling me to wait. We are not approaching March 2024 and I still have not received a feedback, my new phone and my laptop but I am still paying for them every month.
