Very dissapointed

I was at Woolworths Flanders Mall on the 21/09/2017/ 17:35. ********** ********** 3907 did my grocery's and approached the tills and I firstly requested to pay for my Woolworths card , The lady started scanning my items and at the end she requested my card and she used it to pay for the items instead of using it to pay for my Woolworths card even thought I had asked her so many times if she will still be able to make a payment to my Woolworths card . I needed to use the Woolworths card for payments . Supervisor and Manager advised that they cant process a reversal the systems is not allowing the . I'm very disappointed as my budget was messed up . I sent a complaint to Woolworths , they rep**** stating that someone will contact me . up until today I haven't been contacted . for so many years I have trusted Woolworths to have the best service . im very disappointed .
