Shocking Service

In general, I find Takealot service to be great, however in my recent interaction with them I had a shocker which is unacceptable. I purchased and paid for products to be delivered. Delivery guy called a day before the scheduled delivery date and was upset that I was not available for collection. I told him delivery was scheduled for the next day I could tell that he was not happy with that answer. Next day got delivery SMS confirming the delivery was on the way, but no delivery. Same day I got an email stating my order was returned “unable to deliver”. I was waiting for the delivery all day (on Friday) as I needed it for the weekends event. I called and spoke to Sizwe (he was helpful) he said that the products had been returned to the warehouse and that he would arrange the order be sent out again and confirmed this in an email. Then 2 days later (Sunday) I got an email from Rhoda confirming “we have created a replacement order” with a delivery date Then 2 days later got a payment reminder email after the previous email said I should ignore the payment request. I send an email to Rhoda to ask about the order and the payment request. 2 hours later I got email saying payment had been made. Next day got an email saying my order was cancelled and that the product was not longer available. 7 hours later I got an email (response from my previous email to Rhoda) from Tebasto stating that “the order has been authorised and that it is sorted”. I have no Idea anymore what is going on with this order, this process is shocking the products that I ordered are at the warehouse after being returned why can’t they just deliver them to me (I don’t want to hear this is a technical issue and that can’t be done - OVERRIDE it if you have to). This has cost me financially and I would like this to be resolved ASAP by calling me no more emails. I want my purchased products delivered as promised. This is not how you treat your long-standing customer.
