Black Friday TV purchase

Order number: *** I purchased 2 x 32" Skyworth Android TVs on Friday 29 November 2019. The transaction was done online via www.picknpay.co.za. I received a phone call to provide my TV license on the same day, but because I did not have the details with me, I called back the following day to provide the TV license number. I asked the agent who I spoke to whether there would be any delay, he said no.

Upon checking my phone this morning (5 December 2019), I saw that my order had been cancelled due to the payment failing to go through. Payment was attempted at 5am this morning and I was then given until 7am to correct the details on the purchase. As I only looked at my phone after 7am, I missed this deadline. I then attempted to process the transaction again as per the email, but was met with a message stating the the TVs are out of stock.

I contacted online support and I was informed that I would need to purchase the TVs online - which I could not as stated above. I contacted the store where I was supposed to collect the tvs and was informed that the tvs are there, but that they have most likely already been sold.

The reason for the payment issue is that my bank flagged the attempted transaction as possibly ********** and therefore the payment was unsuccessful. I believe this happened because PnP never processed the transaction on the day of purchase. I spoke with Loshnie Pillay (Ops manager? - ***) and she also informed me that the tvs are sold out. She also went further to say that the reason why payment is only processed on the day of collection is that there may be no stock available at the time. I find this quite disturbing - that PICK N PAY, one of the largest retailers in South Africa, operates in this way. How is it not possible to know what stock is on hand at the time of a sale??? Payment should be immediate for items like TV's and appliances - stock levels should be known. Does your SAP system not allow for online stock levels or is everything still batch (processed at the end of the day)?

I am posting here in the hope that someone with authority can reason and hopefully assist. This is a poor showing from one of South Africa's biggest retailers. This has left me quite bewildered and jaded and I am reconsidering using Pick n Pay as my retailer of choice for grocery shopping.
