Very bad service from Pick n Pay

Good day

1. my account was credited twice with an amount of R 3364.00 and R 2660.43

2. I placed my order on Friday 9 February 2024 for delivery on Monday 12 February 2024. I received 2 sale items short, I contacted the online call Centre and was told the items was out of stock, I told the consulted, I was in the store on Monday and Tuesday and they had the item in stock, she told me to hold on, as she called the store. After her call to the store she told me the manager told her they allocate certain amount of stock to online purchase and walk in clients, I asked her where in their TLC's or on their website it states that stock is allocated to online and walk in and she told me it is not on their website or in their TLC's. i then made a couple of calls to Pick n Pay's head office and was told the regional manager would contact me this was on Wednesday 14 February 2024, by Friday no one contacted me, and I called then and spoke to the online manageress and was told she would get the relevant person to contact me immediately, it is Monday 19 February 2024 and no one has contacted me. Bad Service
