Delivery Damaged my Wall - No Accountability

I had building material delivered from Chamberlains Waterkloof almost 2 months ago. The driver, Kenneth, unfortunately struck a low wall on their way out. After talking to the owner of the house, I contacted Dispatch with photos and asked for them to repair the damage. A week later I followed up after no feedback, but the guy who I was talking to, Arnold, was on study leave. I then started the process again by talking to Dispatch and sending photos. No feedback for a week until I followed up. They asked for a quote, I send one, no feedback for a week. I wait another week, then go to the store in person. I find Arnold, who asks for a quote and assures me they will assist. It has been another week since then, and no feedback or answering my calls. Chamberlains is supposedly proud of its customer relations but seems to shy away from taking accountability for their employees actions.
