Vodacoms poor service

Hi. I called Vodacom in October 2019 to report the issue I am facing with reception in my area. I was told that it will be escalated to another department (technical) and feedback would be given. I did not receive feedback and called 3 weeks later to find out why. They said that connectivity was enhanced and asked if it is better. My reply was no and why was I not called for feedback. I wanted to speak to someone handling my query from the technical department but was told that they do not have a direct line and they will call me back. This has now gone on till March 2020 with no resolution. I have a business package on my cell and laptop. With the lock down due to the Corona virus I have to use my MTN sim card to work on my laptop. How does MTN have such good coverage. This is absolutely unacceptable and I need a resolution immediately.
