ZERO CUSTOMER CARE

How the hell am i supposed to even query or make a complaint to vodacom when you cant even get through to their customer care line to speak to them. I have been trying to call all they seem to think is a option is data, sim swap and two other option. how about NO ONE CAN HEAR ME WHEN CALL THEM.?????? is that not considered important i spend so much damn money on airtime because i have to work from home and make calls all day and my clients cant hear me. ***!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
