Billing & Bad attitude

Yesterday i phoned to enquire about a payment that i made to my credit card, and i spoke to a guy by the name of Claude or Todd something like that, that individual was very rude, instead of listening to my complain he was Passing the buck to somebody else, shouting at me, telling me that he won't be able to argue with me, i wasn't even arguing with that fool i was trying to get some answers, if he couldn't answer he should have told me, not hang up on or place my call on mute, i was calling from my cellphone and the last time i checked virgin money wasn't buying my airtime to phone, i had to phone back again the second time and i spoke to Refiloe who advised me that they received the payment & there's an outstanding amount of R200 and something, of which i don't understand those charges because the credit card was paid off in April and the charges were added in May, please explain.<br> <br> <br> Can someone please teach that man some manners he needs to understand what is the meaning of customer service, and also i need some clarity on the outstanding balance.
