No service from Vodacom after days of calling

I upgraded in Feb 2023. The new phone is not reading the Sim card, I have been given the run around by vodacom customer care, vodacom accounts, vodacome after sales departments for days. At one stage my husband, daughter and I called vodacom at the same time and when my daughter finally spoke to someone, they refused to assist her and transferred to another department, only to be told she cannot speak for me but that I need to call them yet we were on a conference call after I dropped my call to vodacom This is ridiculous, I have paid for the upgrade already but the Sim card and phone are not working and no one can assist or will try to. I just called vodacom after sales , the woman answered the call, then continued with her personal conversationa and put me on hold without even greeting me.
