Pick and Pay online deducted twice from my account

I placed my order on the 25 November. The amount of R2407 was deducted from my account. It was more than my order and I assumed it was "the order amount plus a small additional percentage of the total amount is reserved" as stated on the online Pick and Pay site. My order was delivered on the 27 November and the amount for the order was also deducted on the 30 November. Which was a mayor concern for me, is that the R1759 was deducted and the R2407 from my account. I phoned the call centre, who promised me they will send it to the department handling this and they will resolve this as soon as possible, my bank confirmed that the mistake was at Pick and Pay side and if Pick and Pay did not call them the issue can't be resolved. I had to borrow money for my debit orders, because this was not resolved. I phoned them again today for the third time. They still felt that their was a hold on the money and it will be released, which the bank already confirmed isn't true. The more I tried to explain that the bank said their was an error on Pick and Pay side, the more they asked me to "listen to them I dont know the prosess" They insisted it was a hold and it will be released, although it has been 9 days since I placed my order. And even on their site Pick and Pay online banking state it only takes 72 hours. https://www.pnp.co.za/pnpstorefront/pnp/en/faq I then rushed to my bank, with the call centre lady on the line. She put me on hold and did not return. I had to call them again. Standard Bank spoke to her and after my bank made a phone call it was confirmed that is was not a hold, both the amounts ( R2407 and R1759) as deducted from my account. Pick and Pay could not resolve the issue stating the dont have a financial department. Luckily Standard bank could reverse the amount. Now my question to Pick and Pay: How can you not resolve a serious issue like this?? You took the money from my account, their was NO hold on the money and then YOU couldnt resolve it! If this issue was not resolved by Standard Bank, my prepaid electricity would have run out by Wednesday, I would not have any money to look after my family this month! And still you sleep well at night, just saying to your clients we cant resolve this issue or their is a hold on your account.... PLEASE SPARE YOURSELF THE AGONY I WENT THROUGH. THINK TWICE BEFORE YOU DO ONLINE SHOPPING WITH PICK AND PAY.
