New phone faulty

I purchased a new contract on 21/04/2025 (cell phone nr: ***). The phone had difficulty from the start (couldn't hear when I made a phone call, had connectivity problems). Vodacom confirmed the sim card reader was faulty. The phone went in for repairs on 25/05/2015. I have enquiried three times and I still haven't received the phone back. It's really impossible without a phone and an old phone can't be used in the meantime because the sim card is smaller now.
