pathetic service from the edgars group

on Sat 14/02 I went to edgars eastrand mall,I gave the lady the stuff &my account card she proceeded to with the purchase she then made me sign nelectronic device &Dn sed it didn't go through I asked her what did I sign for she said oh you signed like I was not supposed to after handing me the Device . I stood there for 15 minutes she says the system is slow I then told her to cancel my order &acredit my account which took 15 min n i signed for that . I have the slip for this .on Monday I then went to Eastgate branch to buy the cosmetics that i didn't get initially. I was told that i can't make a purchase because i only have R44 avail.i went to accounts &was told there's a purchase made on my account for R 2880 that's hanging I told the lady I left on Saturday not having made a purchase she said it's a system error &the lady that processed the purchase only credited the account once & the purchase went of 4 times I was promised a call on Monday by Pontsho & that the products will get delivered to my work but I haven't got a call &I'm tired of the awful service and empty promises I want this sorted and I made numerous calls to Eastgate with no luck . I want to close my account.
