Lazy customer support staff

Extremely lazy customer support system, have absolutely no care to assist clients regardless of our situation. You can talk to anyone as everything is on whatsapp or the app, you ask for a call back NO ONE ever calls nor can you call them. I gave them proof emails was sent to them i even sent them the report they needed they still tell me wait 2 to 3 days. I ask them to let me speak to a manager, they tell me wait 2 to 3 days. Queries that was resolved 3 days ago, they only give feedback requesting updates when me as the client and the fiber providers have already resolved. There are many unemployed South Africans who would value the job, please fix your processes and resolve
