Damaged goods received, no attempt to replace them

I ordered 6 coffee mugs from Mr Price Home online and paid for express courier delivery. I received 2 mugs badly chipped and requested an urgent exchange as it is a birthday gift and the reason for me paying for the express courier. First I was told I can go to the following stores (none of which were even remotely close to my home...) to exchange... What was the point of me paying the courier fees??? I asked them to arrange for the courier to come and collect ASAP and replace the damaged cups while keeping me updated via email. I received an email today: Your support request has been solved. Really? Not even close. I am terribly disappointed in the service.
