Worst online service

I placed an order with Woolworths on the 09/03/20. My delivery was for the 18/03/20 between 14:00-17:00.I received an email on the 18/03/20 at 17:44 stating that some of the items on my list are out of stock. Today 19/03/20 at 11:00 I received a call from their head office and this person tells me that the order went to the wrong online store which is Bassonia and was supposed to go to Centurion. I have to place another order which might be delivered later this week because she does not want to give me false hope by saying it will be delivered the following day. First of all, I placed an order for essentials to be delivered to my mother who is unable to leave the house due to the fact that she is looking after my daughter who is only 2 years old and also due to the lockdown. This is the second time I place an order and I'm being inconvenienced like this. I decided to make another plan for my mother to get the essentials by using another delivery service. Now, my other concern is how will I be refunded as Woolworths do not do follow ups in terms of refunds when it comes to online orders using virtual cards. I had to spend more money which I don't have due to the incompetence and negligence service received from Woolworths. It is a big company, I don't argue that, but it is my money. This is the second time I experience such horrible service from them as I placed an order in March for an amount of almost R2000, cancelled the order because I was able to get the items myself and yet Woolworths has not refunded me my money. Instead I had to contact them numerous times only for them to tell me I must contact my bank. So now I'll be going through the same hassle only difference is that I did not cancel my order and according to the Woolworths App, the order is a past order.
