Unhappy customer

Im writing this message with tears rolling down as i feel that my right as a customer are violated ,i went to Edgars Cresta to buy two pairs of puma 50% sneakers it was _R799,i swiped my capitec debit card ,according to the cashier she said it declined but on my side i received a message that the money is out of my account,they promised me that it will reverse the transaction after 24 hour which it never did,i went to Capitec frustrated the consultant reversed the transaction back to my account,then i went to Edgars again to pay the amount and get my pair of sneakers , got the receipt successfully but midnight the same day another -799 went off my account ,i went back to Edgars and nice lady named Bongi asked me to bring the bank statement called in and told me to wait 48 hours ,she tried her level best and i appreciate that ,yesterday it was my 48 hours still no money in my account and she was off ,im really disappointed that Edgars doesn't want to take ownership they are sending me from one direction to another like a fool,I've spend so much money going up and down i really don't know what to do anymore,is this how i should be treated as customer? Can i please have my 799 please ???
