Webafrica - Bad Customer Service

I had a simple question regarding an unusual amount that was deducted from my account by Webafrica. After searching for a bit I realized the only way of contacting their support is via WhatsApp. I was then put in contact with Puleng on WhatsApp and I asked why the amount was deducted when its already being debited each month. She seemed either unable or unwilling to assist me giving me one word and sarcastic answers. After repeating her unhelpful answers several times, she then instructed ME to end the chat. I refused, saying that I have not gotten a satisfactory answer from her. She then asked me to end the chat again and when I asked if she is refusing to help me, she then transferred me to someone else without even informing me. My question was not difficult. If an agent is unable to assist I can understand but they need to then escalate the issue and inform the customer. I have the full chat history of this WhatsApp conversation. I would love for a manager to look through it so that they can help their agents with proper customer service and escalation training.
