Being harrased after account closure

<p>Hi,</p> <p>I had an issue with Vodacom after I had accidentally transfered R6000 to their account last year. I posted a review here on 25 Aug 2015 with heading "Payment reversal not being actioned ". Afterwhich Vodacom responded and the guy that had assisted me said they will not be reversing the money instead they will be using the money to pay off the account and that they will close it for me. I then accepted that and requested I get sent a paid up letter but to this date nothing was received. To my amazement Im now being harrased by agents from Hammond Pole saying they are acting on behalf of Vodacom and that I need to pay(the latest agent is Thando Mkhatshwa). Now they are threatening me with a judgement after I told them I do not owe Vodacom. Case Number: HP ********** (According to Hammond Pole). Can Vodacom please advise why is this happening ? Where is my paid up letter ? What happened to that ?</p>
