Quad Debiting of my account

Hi,<br> <br> On the 11th of July 2015, I purchased four tickets online for a movie at Pavilion NuMetro. The purchase kept returning as unsuccessful however my account was debited, after numerous attempts of booking one set of tickets were successful. My account was debited four times @R260 a time to a total of R1040. When speaking to Thandeka T Vilane ( the Cashier) she assured me that by Monday (13/07/2015) the extra money debited on my account will be refunded. It is now the 26/07/2015 and I have yet to be refunded. This is totally unacceptable as Nu Metro have not been responding to complaints left on their website.
