Refusal to return customers money

After being charged a value of R 1599.99 twice last month due to a CNA's faulty card machines I was told I need to provide the store with a bank statement, which I did (Having to take off from work to go have it stamped). The amounts came of my account on 18 June yet I am still waiting for them to return my money and on top of it nobody has provided me with any feedback. This is my second report for the same issue. <br> <br> I have contacted the store as well with no response. This is the worst service I have received in a very very long time. From this experience I would definately take my business elsewhere. How hard is it to get my OWN money back
