Overall Poor Service from Delivery to customer responce to escalation

I placed and order for two items on special. Firstly the delivery was confirmed a certain day (Fri 03 MAY). I received an SMS indicating the order is out for delivery by 17h00 on the specified day. No delivery took place. When I followed up the Saturday, I was advised that the delivery will take place the next business day Mon 06 May. Halfway though the day I inquired what is happening with my order, and I was informed tha there is a delay with there Courier partner, but that I will get feedback. Again no feedback on the 06th of May. When I followed up on the 07th I was pushed from pillar to post and after 5 phone call and 2 escalation I finally found out that my "Part" order is out for delivery. The other "part" however is now lost and they can get a replacement, however they will refund the item. The special I utilized provided 60% discount. Takealot is not willing to compensate me for there mistake I lost out on opportunity cost on getting hold of similar value. Again overall a very poor service with the customer never getting any feedback and there online systems not supporting the "story" they now provide. The order in question is # ********** 6. Lets see how they now treat there customers. Everyone please be aware you are only a number with this business and if you do or dont do busniss with they they do not care
