Markham Sandton deficient service levels

On the 28/07/2023 I went into Markham Sandton, the jean I wanted to buy was priced at R799.00 and when I got to the till point it was now R899.00. The cashier called the manager Thabo, who advised he'd to rather cancel the transaction and refund me, no apology, no admitting of any fault. This was done as I stood there in disbelief at the service and the disrespect I'm being afforded & I was not going to stand there an argue as he felt I don't deserve better treatment. The transaction was cancelled and I was sent money from the cashiers PERSONAL ACCOUNT!!! that was meant to be my refund, in what world is this done? I'd like this issue attended to and feedback given.
