Return customer

ON the 19/04/2025 I went to Relay Jeans Greenacres mall Port Elizabeth to do a return of clothing I bought the cashier that assisted me told me that they don't have money the cash for the day has been banked already an i should rather go to Markham to do the return. I went to Markham explained to the cashier what happed at relay the cashier then phoned relay asking why they didn't assist me they then suddenly had the cash to refund me an told the Markham cashier to tell me to come to their store. I'm very unhappy their customer service is beyond phatic it's a disgrace
