Worst retail buying service in South Africa (and I have used many of them)

This app and the experience with the actual service is sadly a fail. Starting with the challenges of the address the app identified and which it would not recognise for delivery. I sent explanations before to their help centre but never received feedback directly would wait and then eventually just close the app, then to actually ordering today and noting the following: 1) The cost of the items are more than in the retail store. I am happy to pay for this if it offers exceptional service. However, other than a very kind shopper contacting me, there is nothing else, and these amount are not small amounts. 2) The items available, which is the only reason I am using the app and not going to the store myself, are not actually available. I would understand this on a cheap app, where I am paying what I am and therefore don’t expect that “exceptional” service. The kind shopper could not find any alternatives. The bigger one is they are charging more than the sale on their own app and charging a concierge fee and I could then rather use the Woolworths Dash app and get products in real and quick time, not pay a delivery fee and actually get the products in the agreed timeframe, which is an hour not three. In addition to this, I could order from Absolute pets online store, get a next day delivery and pay a delivery fee, which is still less than the AVO markup and concierge fee. 3) The blank (yes you are reading correctly) final invoice I get is still not reflecting a credit for the product which is not available. And if it is blank, it is unprofessional for what AVO is trying to do. 4) It is not 12:38 (the order was made at 8:23) and it has still not been delivered even though the blank invoice was sent at 9:32. No calls, no whatsapp messages absolute silence. It is also in the 10-12 window. Not a solution and I am back to getting my goods delivered through the apps of actual companies directly as I see absolutely no VALUE in this service whatsoever.
