Shocking service

I purchased some clothes from Edgars menlyn on Sunday and when they first swiped my debit card, no slip printed, so they said no money was taken from my bank account even though I showed them the notification SMS that money was deducted from my account. They swiped again and ensured me the first transaction would be reversed in 24 hours. They also ensured me they would call me the following day to confirm it. 24 hours later, no call, no reversal. So i went back into store and told I need to bring in my bank statement to get the transaction reversed. <br> <br> Why on earth should I need to bring a bank statement to fix a system error that was entirely not my fault. Please sort this nonsense out and return my money that you promised to return already.
