Dash should be bashed!

Currently on a call on hold for 15 minutes as I type this. When making Dash orders, the App does not allow one to select the substituted item of choice (it provides its own options none of which I want) and when you type it in manually, you can't find it. So, when placing the order and chatting to the so-called personal shopper, I asked to be contacted for substitutes as all items were important only to find that the shopping had ended and two important items were missing. Why am I paying R35 for delivery if I can't get all my items even after specifically asking to be contacted? When I call the customer care line, the consultant tells me that I will not be charged for the items. That's not the point! Then he puts me on hold only to come back and tell me that I didn't select the items as an alternative. What part of "I couldn't select the alternative item", did he not understand? That was the reason for my request in the first place. The consultant I spoke to was Sipho and he seemed extremely ill-equipped to deal with basic comprehension. I asked to speak to his superior Tshepi and I was told she was on a call and will call me back. Terrible service.
