KOLONNADE MANAGER AND CUSTOMER CARE - USELESS

We went to the Kolonnade movies the last weekend in July 2019. The cashier make a mistake with our tickets and we paid twice - she ensured us that the credit would appear for the double payment within 24 hours. To date I have not received my refund of R332.00 - I have had to submit copies of my bank statement for the day and 3 days after the original transaction and Simpiwe from Ster-Kinekor argues that the transaction "didn't go through" - even though my bank statement clearly shows the deduction and my bank confirmed that the debit was honoured and paid to Ster-Kinekor. I have sent several follow up emails with no joy..... I continuously receive new references but Simpiwe now ignores my requests, the manager from Kolonnade doesn't respond either.... Worst customer care and manager I have ever come across
