Shoprite managers with terrible customer service skills.

Today I went shopping at the mount edgecombe shoprite and after picking my groceries and going to pay was I told that my card had declined. We tried the card a few more times and it still declined which is what prompted me to check my banking app. After checking my banking app I had seen that my money got deducted for the cost of the groceries and was addressed shoprite. I raised this with the cashier who called her manager crystal. Crystal came with a disgusting, non helpful attitude and addressed us. Crystal went on to say that they cannot release the groceries in which we paid for already until it reflects on their side. This manager crystal used the company policy to justify the way she treated us and there was a sore lack in her customer service skills. After letting her know that we will not be leaving without the groceries she told us that we must speak with her branch manager. We went to speak to the branch manager who refused to address us and ask us what the issue was instead he asked crystal. The branch manager named tony was absolutely disrespectful and refused to assist us in any way whatsoever. He said that we must come back again and bring a bank statement and hell see what he can do. Now we took an uber to get there an uber which costed almost R100 and tony expected us to do it again because of his stores under-updated and under-maintained point of sales. I then told tony that I will not be leaving without my groceries in which tony rep**** "trust me you're not walking out of this store with anything." I then let him know that these were items I had paid for and that i should have my groceries to which he rep**** "Don't challenge me." DON'T CHALLENGE ME!!! Is this the type of managers that shoprite appoints. Managers who sorely lack empathy and customer service skills. Im utterly disgusted because imagine being a customer going through something like this, paying for groceries and not having much money left after and being in this panic because now your money is gone and this is the way we get spoken to. I can promise that I will no longer be shopping at shoprite and neither will my family. I humbly advise shoprite to get their manager and branch manager under control and give them some customer service skills and some tips on empathizing with customers coz this was absolutely disgusting and appalling.
