Horrible customer service not getting what I paid for

I've ordered concrete from Larfarge they charge you per Cube my husband worked it out and I paid for it up front because that is their policy. We then booked a day and time for delivery . On that specific day of delivery they contacted my husband at the time delivery was expected to day they running late and will be there an hour later. An hour later they contacted my husband again and confirmed they running late and it will take another hour to get to my house. 2 hours later they finally came the driver was in such a rush and just dumped the concrete and left. The product was short by more than half a cube. My Husband then had to run around to buy extra sand, stone and cement in order for our contractors to mix concrete. The following day we contacted Lar***e they informed us that we have to speak to the manager and they will get him to contact us we finally managed to speak to him a day later he confirmed that he will investigate. He came out to my property to work out the amount of concrete that was delivered so he could work out if our calculations was correct. We had to contacted him twice before we got hold of him and he just confirmed that they discovered that one of their machines leaked and the concrete ran out on the floor. ( Surely when we questioned initially they could've discovered that) and just said they will email me forms to complete for a refund or send the concrete its up to us. He didn't apologise when my husband spoke to him when my husband informed him about the bad service and that they showing no remorse should we just go to the Media he stated" That don't work anymore" If we hadn't questioned why the concrete was less they would've never informed us and that is *********. It made us feel like a nuisance " a Cube of concrete is R1400.00 " and that is our hard earned money. The service we received was pathetic.
