Lumka Kuboni is useless

Called RCS and got through to Lumka Kuboni. This agent was incredibly rude and unknowledgeable about my account. When I asked her why my account status was so much in arrears, she told me it was because I had paid in advance and that was not allowed. Lumka Kuboni does not have people skills to be a call centre agent. Lumka Kuboni does not have proper language skills to know how to talk to customers. Lumka Kuboni does not have sufficient accounting skills to explain the basics of customer accounts.

Fortunately I did get through to someone at RCS who managed to explain the account status properly, so payment will be made today. But Lumka Kuboni should not be working at RCS. She is useless.
