Hopeless Vodacom

Absolutely hopeless. I have been trying to cancel a few contracts, but have been unsuccessful since October 2019! I have phoned ....holding on for a long time and eventually pressing 2 as instructed to be called back. This has not happened. It is a disgrace that a company like this keeps on getting away with hopeless service. Service is only good when they want to sell something. Perhaps a class action by all the disgruntled customers will bear fruit?! How does it work that a company who is in communication is impossible to communicate with?
