Takealot customer care is pathetic

I ordered a 10kg bag of dog food and one other item. Delivery date was supposed to be Thursday 28 March 2019, on the day the order was due to be delivered I received an sms stating the order would be delivered one day later. Yesterday my housekeeper went out to sign for the delivery but only one item was delivered - not the 10kg bag of dog food. I immediately phoned Takealot and informed them of this and that they needed to get hold of the driver to come back as he did not deliver the dog food. The person I was speaking to then cut me off. I called back again and spoke to chad Lazarus, after holding on forever he informed me that there was a problem at the warehouse dispatch, he didn’t know what it was but there was an instruction not to dispatch my two items together. I informed him that it is common courtesy to inform your customers if a product is not going to be delivered rather than being left in the dark. He assured me he would immediately look into it and gave me a reference number and promised to call back shortly. I am still waiting for the call. On top of which takealot had the cheek to send me an email to review the service that I received from chad lazarus. Last night after numerous emails were sent to takealot to give them my reference number to try locate my missing 10kg bag of dog food, they sent me a reply stating that the order was delivered and signed for by my housekeeper. I am at my absolute wits end! Takealot is run like a circus, their customer care is pathetic.
