Terrible experience with One Cart

HORRIFIC experience. Order was placed 2 days ago for delivery today at 12. At 2pm a random WhatsApp message came simply showing an items picture and the words “no stock”. Not even a mention of who this was. The profile picture of the account was also terribly inappropriate and unprofessional. After multiple calls back and forth we kept being told that the driver would be there shortly. This never happened. Eventually they arrived at 6pm with our order and we had told the customer service rep that we are concerned that the food had been sitting in the drivers car all day. Needless to say, the frozen items were completely thawed when they arrived. I asked the driver when he collected the items from Woolworths and he said 4pm but there was traffic coming from canal walk. I live 10-15 minutes from canal walk. 30 minutes max during traffic. He couldn’t explain the 2 hour time difference. I am not prepared to risk consuming any of the food delivered as it all required either refrigeration or freezing. I have used Bottles and Checkers 60sixty and they are brilliant. One Cart? No thanks. Very unprofessional. And they do not seem to vet or train their shoppers and drivers. Avoid. There are much better options.
