Vodacom and Vox- Failure to fix internet

Both companies have been unreachable for 3 weeks, whilst we haven’t had internet at home, but still continue to pay. We have been contacting both companies and each time we’ve been given a new operator. Each one with a different excuse as to what the problem might be. When we insisted that they start responding to the problem in week 3, the operator from vodacom put the phone down in the middle of the conversation. This is unacceptable and terrible service from both vodacom and vox. They are blaming each other and we sit without a service for which we are still paying.
