Online Order complaint and terrible customer service

Ordered a computer and a phone on black Friday sale, within 2 days of each other, on the 25rd and 28th November respectively. Still have not received my products, I've been hung up on by customer service, even had to escalate the earlier order to a complaint. Still waiting, apparently meant to arrive tomorrow (6th December) which is way out of the delivery timefrane of 2 to 5 working days. Very very unhelpful customer service agents on phone, chat and email. Rather buy it from a store. Incredible connection needs to get their act together with deliveries and be more honest with their customers, especially when one is spending 20k at their store /online store. Have received 3 smses that the order is out for delivery only for it to be cancelled by them just before 7pm
