Rude and *********** Call Centre Agents

You are the worst service provider in the country! I have called your useless call centre almost monthly due to my airtime getting depleted mysteriously. This is a time consuming and frustrating exercise, as you have hired the worst call centre agents ever. They are dismissive, rude and inefficient. I recharged with R 200 airtime which has disappeared. Your call centre agents says I must call back after an hour because the system has not updated yet, I waited and called back after an hour and another agent says I must call back after an hour. What NONSENSICAL ******* is this? I constantly dial *141*5# and *136# to unsubscribe whatever ******* your system subscribes me on, without my knowledge, to avoid my airtime disappearing. Why do you have those people sitting there, if they cannot assist?
