Inefficient call centre

I have a cheque account that was handed over from Standard Bank to Anthony Richards and Associates debt collectors. After relentlessly pursuing me to settle or arrange to settle this account which I had made a promise to do, I made a first payment as agreed. I then requested proof of this arrangement in a form of an arrangement letter, which I was told would only be sent after payment has been made. I have since made the payment AND emailed the proof of payment but I'm now being told that three installments must be made before such a letter is issued. <br> <br> When I get frustrated for obvious reasons both the agent and supervisor were very unprofessional, not to my surprise since every agent I had dealt with was either *********** or just plain clueless. I have been calling for a week and every time I have explain from because their so \systems"now all of a sudden don't record calls or notes for calls. The supervisor went as far as saying \""I'm going to speak to my manager SEEING AS YOU're SO DESPERATE FOR THIS ARRANGEMENT LETTER\"". Unprofessional as she was"
