agents are very unproffessional

Such pathetic and unprofessional service i do not expect from Ackermans, the account has been paid on 2018/10/12 with outstanding settlement amount R3086-46, yet to date i'm battling getting my paid up letter i send e-mails which i'm not getting any feedback, and i make calls agents are just clueless of what is happening, the e-mail with proof of payment was sent to customer service where ELSONIA PRETORIUS forwarded the e-mail to collections, now on call with Vuyelwa for almost 15min who just said she is transferring the call to collections department upon asking her what for she just completed the call transfer to collections.when i got through to collections the lady confirms that yes they did receive the proof payment, so now my question is what was i suppose to send the proof of payment for the second time ?where did you get an uns****ed agent, she needs to learn how to deal with customers in a human level the power invested in her a representative of Ackermans gives her no right to make any stupid judgments cause according to her she was certain i never paid i'm just claiming money and that makes me wonder about a whole lot of things.I have been given next week Monday as i turnaround time for allocating the payment, I am not gonna make any follow up calls please make sure I get my paid up letter soonest.
