WOOLWORTHS DEDUCTING MONEY TWICE

I bought clothing online at Woolworths that amounted to over R900. This money was deducted from my bank account and about a week later the amount was deducted again. I contacted Woolworths and they said that they would reimburse me. Its been a couple of days now. Still no money in my account. I will NO longer be shopping at Woolworths and I WILL TAKE THIS FURTHER.
