Disgusting service from Woolworths Dash and Staff

I have just had the worst experience with Woolworths Dash, who I order from regularly. I placed and order, with the instruction to only substitute items after speaking to me. Most of the items are out of stock and when I spoke to the shopper Thabisile she was rude and didn’t listen to me. While I was on the phone she was speaking to someone and said “should I just drop the phone” I then called the store Benmore to be met by another rude person on the phone, who first said “What!” When i asked to speak to a manager and then told me there is “no manager in the store” To add insult to injury, I am waiting for funds to come in and only had R1000 for dinner which will now only be credited to my account in 24 to 48 hours. What should I feed my family for dinner? I have never had such a shocking experience with any retailer, and it is very disturbing that a loyal customer that uses Dash regularly gets treated like this. If I could this woul be a zero star review!!!
