Poor service from vodacom

Why is it that I am battling with my vodacom internet? My phone (Samsung A52) is about a year old and most of the time my phone indicates that there is no internet service. This happens in Centurion, in different areas. (Eldoraigne, Wierda Park, Valhalla, Clubview) And this is not when there is loadshedding. I have sent a message to vodacom via Facebook and was advised to send my cell number to them via Facebook messenger but once I do this, I receive an automatic reply with a bunch of options to select.

This is POOR!
