Checkstar robs customers daily

This incident had occurred on the 10th May 2025. I had swiped my card for a purchase at the overport branch at 12.00pm the cashier did something quickly on the pc and stated my purchase was declined. I contacted the bank immediately and confirmed the purchase was successfully processed. Devrani approached the till and requested to swipe once more despite me proving that the purchase was successful, I comp**** as Devrani confirmed that the amount will be reversed and if not I would have to bring in a bank statement. On Monday another transaction was processed by checkstar for the same value at 4.09am verifying a 3rd amount deducted of the same value. Monday 12th May 2025 afternoon I had taken my bank statement to Checkstar overport which was received by Mumtaz to be given to Devrani the next day. I called in Tuesday morning requesting if information and documents was provided to headoffice. Devrani called back and confirmed she is handling query. Tuesday 13th May 2025 I received a partial refund. Wednesday I went in and was advised no feedback was available for the 3rd amount taken. I have been back and forth between Checkstar and my bank as my bank has confirmed that all 3 amounts of the same value were banked by Checkstar. I have provided documents and made efforts for all requests on my own dime. I just want my money refunded as Checkstar won't compensate me for running around using my petrol and alternative costing to sort this out. I'm not the 1st customer this has happened to and I won't be the last. The cashiers love committing ***** on the daily
