Edgar's double charged me, 4 years ago.

I purchased goods to value of a thousand rand 4 years ago at Edgars Gateway. The manager, Sibusiso told me he can't give me a recept because the printers are working. I insisted upon seeing his Manager who then printed a till slip at another machine. He gave me a 10 % discount because of my time and no recept upon payment. Instead of this guy crediting my purchase, he debited it . Now my bank transaction shows 2 debits. Both Sibusiso and his manager insisted that I wait a day for their system to put matters right. I waited weeks, then contacted Edgar's. They couldn't locate Sibusiso or his manager. I went in personally several times but was told these people could not be found. I tried calling and visiting other Edgar's, in Pavilion. And even in Johannesburg. I was told to email a lady Mrs Chetty, who did nothing to help. I would call the Edgar's in Gateway through out the year but without help. Thus went on now for 4 years. Can you help. Some Edgar's branches gave me numbers to call but I was not happy. I received a call from a lady in Cape and she told me she will help, but didn't get back to me.

Thank you.
