Useless !!!

What is going on with Vodacom signal lately? I have coverage and my phone shoes 5G but I can’t do anything, and it is everywhere I go. So it is not an area coverage fault. I pay almost two thousand rand a month and this is what I get? Why should I keep on paying this when I cant even use my phone or it’s connectivity. Useless is an understatement. Even my phone calls don’t come through ? How is this acceptable !!!?? I have switched my phone on and off, took out my sim card, switcher airplane mode on and off, switched from 5G to 4G, and still nothing.
