Rough handled and mistreated boxes - damaged and opened

I had 4 boxes couriered from JHB to CPT containing clothes and other personal items. The boxes I used were purchased from The Courier Guy offices and were double wall Pudo brand boxes. The boxes arrived in CPT damaged, broken and two were open with one of them having some of the contents fallen out. Looking at the state of the boxes, it would be clear to anyone that they were rough handled and mistreated for the boxes to break in that manner. I have sent pictures to the support channel and have not heard back since. After this experience, I would not recommend The Courier Guy.
