Worser service ever!!!!

I am trying to make a payment arrangement since last week. 1st no debit order was arranged because no mandates was sent. 2 I requested a proof of PTP I was told it has been sent a week ago, nothing until now. 3 spoke to a consultant named Lihle today to follow up, her manager Thayne Santos told me he is too busy with coaching to attend to me and sent another rude and abrupt consultant named Masiviye who dropped the line on me. Their service has been so horrible, I can't settle my bill because they are ***********!!!
