Disgusted at Customer service agent.

My colleague tried to do a billing enquiry. When she expressed her concerns the agent named Lungile laughed at her. We were witness as she put the call on loudspeaker. I am disgusted at the level of service my colleague received. I myself am a Rain customer and I recommended her to use your service. Initially she was told there is coverage in the Chatsworth (Cape Town). The agent that helped her clearly did not have knowledge. She then took home the router and it did not want to connect. She called Technical and was informed there is no coverage. She was informed to wait for the billing department to call. They did not. She then took the router to the Rondebosch branch. She eventually got a refund. She used about 1gig on the mobile SIM. She understands that she needs to pay in a small amount for use of the mobile SIM hence the reason she calls today as her account was trying to be debited. All she wanted to do was get clarification on the debit trying to go off as she never gave Rain any authority to debit. She was then laughed at by this Lungile agent who refused to give her surname. She also kept speaking over my colleague. I am really disappointed in the level of customer service. The agents are the literally the face of the business. If that is the level of service, they are giving customers then you need to close your business. I work in a medical customer service environment and if I laughed at a patient like LUNGILE did. I would have been fired. I will not recommend Rain anymore.
