Late delivery + false advertising = no delivery

Festive season is complete but this story really bothers me, on 20-12-17 I placed an order for a 1TB Seagate HDD, price was listed as R573 and I had a voucher that I used to lower it to R498. When I placed the order I opted to collect the unit to save time as I was in a rush and it said the expected release date was 29-12-17. I thought everything was ok but shortly before 'collecting' I checked the site and now the delivery date was moved to 08-01-18, I called to complain about this and was told I'm not the only one complaining about it but nothing they could do, worst part was that there was no notification of the change of date. Anyway I explained I opted to collect because I was on leave that week but since it wasn't arriving then they should deliver, consultant updated the system to reflect this and also told me that the date she sees in the system is 06-01-18 not the 8th. Either way I wait...come to today (8th) I get an email from Loot basically saying 'oops, there was a pricing error on our site, we'll refund your money and here's your voucher back too'. So I've waited nearly a month and I have nothing to show, I pointed out that CPA says: A supplier is not bound by inadvertent and obvious errors in price display, provided the supplier corrects the error and take reasonable steps to communicate such an error and the correct price to consumers aware of the incorrect pricing. A new car for sale with a price of R21,000 (instead of R210,000) displayed is an obvious error.

I pointed out that taking nearly a month to realize a pricing mistake and then leave the customer with no sense of recourse or satisfaction isn't reasonable at all but this doesn't seem to have made any difference at all. I've told them it's the last time I ever purchase from them again and tonight I placed an order for the same device from takealot for R829.
