No Feedback Clearly couldn't be Bothered

I had an Edgars Account which was in arrears. I then fund out that the account had been handed over to RL Daly. When I contacted them I was advised that I qualify for a settlement discount & was given the settlement figure. On the 15/06/15 payment was made to edcon but it was erroneously overpaid by R4500. I contacted RL Daly immediately & was advised to contact Edcon which I did. I was told to email everything through to the accounts department which I did. I have probably sent over 15 emails with all the relevant docs attached (settlement letter,ID,banking details,confirmation of erroneous payment). This has been on going since the 17/06/15 & I am yet to receive any feedback. They made a payment of R145 on 30/06/15 & when I was called & explained this was wrong I was told they would come back to me the next day, this was on the 01/07/15. Do the accounts staff just not care or is it that they are so inadequately trained that they do not know how to sort this out. I am appalled that I have wasted hundreds of rands of airtime trying to call the call centre only to have my calls cut, spent hours ensuring comprehensive details are in my email correspondence only to get automated reply
