Poor service and extremally disappointed.

Called in yesterday to do a chargeback. The call "drops". Call in again and the agent says that she is going to transfer me. The line goes dead again. So I wasted like 30 rand and thought Ill try again today. I buy some more airtime, speak to the agent and the call drops again after explaining my query. I call in yet again, eventually I get through to an agent to process my request. After going through all the motions he puts my on hold but first confirms my email correctly as he wants to send me a form. He puts me on hold and bammm the call drops again. It really seems like your agents are actively trying to avoid certain call types. My issue with the last call is that, you had and confirm all my detail. Where is the email and why not call me back?
