Re ember*****t

I swipe for a shoe that costed R270 the machine then said decline I then swiped again and the same thing happened I had no choice then to go draw the money. However both swipes went off on my phone stating that the money was deducted from my account, this was now 270 by 2 (540.00) I then ask the sop assistant to check and she printed the machines daily print for that day it didn't show. This took place Saturday 28 February 2015, I left it and went in to standard bank for a statement and on my statement it showed that the money was deducted. I then took the statement to the shop and they still denied that there is nothing in their account, I then called standard bank to log a call and the guy that handle my query stated that he can see the money was deducted twice and that his not sure if it's laying in standard banks account or the shops account they will investigate it further this went on for a month i I then decided to go into the branch at cape gate where I spoke to the manager Cindy, she sent the query to the necessary department and it's been more than two month I have yet not relieved my money, this is the bank that controls my account yet my money goes missing and no answer
