I want my money back

I purchased clothes on the 27th of July 2015, I swiped with my card as I was paying. I got an sms from my bank that the payment went through, I even showed it to the cashier. For some odd reason she said the payment is \hanging""; meaning I was supposed to get my money by the 10th of August 2015 the latest. I didn't get the money; I waited till I lost hope; I went to them today; the 17th;they said they will call me back but they didn't. Its 16 working days later but there's no payment made into my account. Can you help me get my money back in cash now because I have waited for too long."""
