Onecart disappointment

This business is obviously struggling. I have had too many frustrating experiences. Their whatsapp customer service number does not work as no one responds timeously to queries or complaints. My order was not delivered - I was told to call the driver and when I did he was flustered saying he left my order because they are giving him too many orders and he has no space on his bike. No one bothered to reschedule another driver, instead when I was disconnected no one bothered to call back to resolve my issue. The APP says that my order has been cancelled because they were not able to get hold of me which is blatantly untrue. The App also says I have been refunded, which is also not the case, meaning I have to call again to figure out what is happening. When I call I’m told that’s not the case, there is another driver assigned to my order. They were meant to deliver at 11:00 and it is nearly two and no one has bothered to communicate what is happening. This is poor form onecart - I was so pleased with this business offering. But perhaps you have bitten off more than you can chew.
