Shocking delays in TakeAlot delivery time and contact difficulties

My wife ordered an assortment of goods on the 13th of January. She followed up on the 23rd with a phone call and heard nothing by the morning of the 24th. I phoned and was told that the delivery will be on Monday the 28th. I requested to be put on hold for a manager, who was not available and I ran out of talk time (I am phoning from outside of South Africa). I went on the mobile app, looking for an email address or complaint area to express my unhappiness but could not find such an area. I phoned again, and asked to speak to a manager again. I was put on hold for ten minutes and then gave up. We ordered more than R 1000 worth of items and reasons given like that stock had to come from warehouses in JHB does not really account for such a long lead time. From the 13th to the 28th? Really? And then the difficulty to get hold of anyone in charge to complain to. Really very poor customer service. Order number 61 28 67 51. I will think twice before using Takealot again, which is unfortunate because I need a lot more items. It is faster for me to get items delivered via Amazon in the USA than to get a local delivery in SA completed.
