Pathetic service

I have been an account holder with Vodacom for ten years or more. I have been trying to cancel one of my lines with them since May 2020. Each time I am told the line is terminated. On 12/8/2020 I was again told my line is terminated. What a lie. This morning I called as I note I am still being debited and billed. A call to custimer services says there is no record of cancellation request. They cannot assist. Told to call 1958 well thats worthless as the call rings and ends (same result for 3 months). Previously they emailed me to say they cannot call me back as they do not have out going lines!! A communication company that cannot make calls? In the mean time I pay the price and this despite loss of income owing to covid. Vodacom service is absolutely pathetic and disgusting
