Money owed to me outstanding for 3 weeks in stead of 10 working days

I have accidentally transfered an amount of R10 000 into my Edgars account instead of R500 on the 26th of July. When I got at the store to ask them how can I return the money into my account they said I should bring a colour copy of my ID, a letter stating what happened and my bank statement for the last month on which the transaction reflects the payment of R10 000. I swiftly went to obtain all the documents and gave it in at the store. About two days after I handed the documents in at the store the lady phoned me and said I should have a certified copy of my ID, so I went to the police station and got it certified. I went back to the store and gave them a certified colour copy of my ID. About 3 days after that the lady phoned me and said that my copy of my ID is not clear and they cannot see my face only to realize that the scanner on which they scanned the copy of my ID cannot scan in colour but only in black and white so I went to the store again and scanned it in on a colour scanner and sent it to ********** as well as ********** as the lady from the store told me to. I received a email the following day saying that all the documents is in place and they will process the payment within 10 working days. I should have had the money in my account on the 15th of August 2015 which off course I didn't. I phoned the customer care line on the 14th and asked how far the payment is wherafter the person told me that I should get it by the latest Thursday the 17 of August of which I also didn't. When I phoned them today the person told me that nobody from the finance department was actioned to do the transfer. I am really really disappointed with this situation, I am in dire need of the money and the feedback from the customer care line is that the transaction hasn't been actioned after I called numerous times and every time the person says that I will get the money, I mean come on how difficult can it be to pay my money back, my account details and everything is on the letter that I wrote.

I am seriously thinking about closing my account because when you owe money to a credit provider they can easily blacklist you the next day but if they owe you money it's fine to not receive it for 3 weeks.

I am extremely upset.
