Unproffessional Behaviour

Today I called capfin at 12:55 and spoke to a lady called Amanda. I explained to her that i had made payment arrangements and not I'm getting calls saying that nothing of a sort was done. I explained to her that i had requested to be debit R720 on the 21st of June. She advised my that my account was in arrears and i told her that i want the debit order to go off and i will also try and make manually payments on the 31st of June. She was very rude and kept on interrupting me while i speaking. She wanted me to settlement the whole amount by the 31st and i advised her that i don't have that kind of money, She then started raising her voice at me and not giving me a chance to speak. I than asked to speak to a supervisor she said to me NO i cant speak to the supervisor because she is still speaking to me, i asked for team leader which was conveniently on lunch. This lady was extremely rude to me and would not listen to a word i was saying. I cannot deal with such people and i demand an apology and respect that i deserve as a customer. You cannot just conclude what is best for you and assume its right for me. I want my account to be sorted out as well
