Vodacom Fibre - No customer care

In February 2024 I was billed for a fibre installation, not sure why as I have had the service since March 2021. My line has been dropping and coming on during the course of February. I have made several calls and emails to no avail. To date my emails are not being attended to. I have asked Vodacom to cancel my contract due to the service I am receiving and again no feedback. I have had cases that when I called accounts the phone was put down due to my persistence in them not addressing my problem. You are supposed to be a telecommunication company yet you lack the communication.
