Takealot to be held accountable not the customer!

Absolutely appalling service from Takealot. They have absolutely no regard for their customers. I ordered and paid for a UPS that showed IN STOCK CT|JHB on the 4th of Feb, the estimated delivery date was the 6th of Feb. On the 6th, the estimated date changed to the 11th of Feb. I logged a ticket today, the 12th only to be told my parcel was lost in transit and that I will get Takealot credits as the supplier has no stock. I find this unacceptable, how on earth is this my problem? The worst part of this is that now I'm unable to find a 2000 KVA UPS for R1550, which is what I paid for it at the time. Obviously with the electricity issues in SA at the moment, prices has gone up. At what point are companies being held accountable? In all fairness they should be seeking a replacement UPS at their cost, not at mine.
