Suspicious purchase on my Edgars account

on 13 Aug a suspicious amount of R485.21 was charged to my account. I started phoning, emailing and replying to 'outstanding debt' sms stating that I did not make the purchase. I received an email from edg******* on 15 Sept stating that this was a mistaken take on balance. I left it there, then end of Sept I started getting calls to pay the outstanding debt as I was still only paying my Club fee, accident & personal insurance fee. 3 Months on and heaps of emails and calls later, plenty of re-explaining my predicament and still I get calls from the collection dept. I have spoken to many of Edgars staff who know about my story and the last 2 have agreed to refer this to the ***** dept. I asked the 2nd last chap 'Dikoleng' to freeze my account as it seems to be compromised. I am sick and tired on speaking to call center agents and re-explaining the issue over and over again that I have closed my club account, and want Edgars to close my account. I have not set foot in an Edgars store in over a year and yet they claim I made a purchase on it. Please email me a copy of the receipt where I signed for whatever was purchased.
