terrible service from the call centre agent

My dad has taken wifi connection with Vuma, vodacom is the service provider. 1st month it was working well no issues and the second month they didn't debit his account and the service was disconnected. He paid via eft after a couple of days after we checked and realised that he is owing. My son called vuma and vodacom to assist with connectivity and was advised that as soon as they payment reflect the service will be restored automatically. It's now been 3 weeks, still no connectivity and we have called Vuma and vodacom no assistance. We have SR number and case number, you get different stories from the call centre agents. We are talking about a pensioner and i'm staying in another city. I have to make calls on his behalf to Vodacom and have to add him on the call for authentication. I'm using my airtime to make a call and worse these call centre agents don't have the courtesy to keep thier stories aligned. My understanding when you log a case, all the information should be noted on the system don't expect the agent to ask me about the issue when i just provided the case number. Vodacom fibre connection and Vuma please do better.
