Edcon not refunding me for money paid incorrectly

My husband while paying his credit card from my ABSA Cheque account accidently paid the amount of R150.00 into the wrong EDCON beneficiary account on the 31/03/2015. I fail to understand why the money was not reversed back to my bank account, why nobody of EDCON tried to make contact with me after the money was paid into an account which had been closed more than a month ago. This means that this account is still open despite the fact that I phoned EDCON on the 25/02/2015 at 08h22, was given reference number ***1 when I spoke to Terrence when I instructed him to close this account. So if I didn't query this does it mean the EDCON would have kept the money? I find this extremely dishonest. The fact that I have closed this account is the best decision that I have made. We only picked this mistake up a few days ago and we have had one story after the other. I was told last Thursday that the money would be paid back to me within 48 hours. I am still waiting for the refund. This query has been faxed and emailed. I have received a few reference numbers for every time that i have submited this query - # WS0530 FX***1T***/ #WS0530T141834
