Poor trained service customer.Complaint Ref number ***

I phoned this morning to follow up my application that doesnt show on the online tracking system and even via the phone.Unfortunately,there is a lady who treat me of Rude while i was explaining her that it s useless to give me a answer which i have alrdy got 10 times in 3 weeks. Lucky me i phoned again and Mr Mbali was professional and assist but I m still waiting for a fredback. People should know that they are sitting in Call center because of us(clients).We are not begging for a service.Thanks
