Vodacom Customer Service Sucks

Even though my wife and I have been a Vodacom customer for over 20 years, they have ignored a complaint I lodged with them on 18 March 2021 about my nearest tower not functioning when we have load shedding or power outages which suggests the backup batteries are faulty (if they even have them). This results in me not being able to make calls in many cases as the tower which is further away provides a very weak signal. They have phoned me on 23/3/2021 to tell me the matter was being addressed, but since then they have ignored my emails and Facebook messages about this issue.
