Online System not backed by proper process

On the 5th of August 2020 I placed an online order ***) for bulk cement, paid for it and the delivery was scheduled for 29th August 2020. On the 12th of August I called the Customer Service call centre and spoke to Celeste Bezuidenhout and asked if she could check if my the delivery has been confirmed with the Supplier and she said yes I will receive the order on the set date. On the 21st I called again and spoke to Lameeza, whom was going get back to me by the 24th but never did. And when I called was asked for Lameeza surname, which I didn't have. On the 25th I spoke to Vuyo and Celeste again to get confirmation of the delivery of the order and they also said I will receive the order. I explained to all of them that I had already paid for other materials with other suppliers that I will have to take delivery of by a certain date or else pay the increased price, and they still went further to confirm that I will receive my order as per the set date. I also spoke to Dikeledi and Ntsoaki (from Builders Superstore Sebokeng) who couldn't find the order on their side and also spoke Daniel Van Wyk (from Builders Warehouse in Bedworthpark) who couldn't provide status on the order. And guess what here I was waiting at the site from morning till noon to receive the order and wasted my 5 hours which I could have used for other things. Can somebody confirm delivery of the order or else just do an immediate refund so that I can go buy elsewhere since I cannot afford any more delays. Honestly speaking I am disappointed with Builders Warehouse Online system, it looks like there are no proper processes supporting the system, Customer Service agents cannot see who placed the order with the supplier and are not even able to follow up on the orders to provide customers with proper feedback.
