Takes over 6 months to find my tires

Around October November of 2017 my vehicle went on for repairs at Durban panel beaters, my insurance requested to replace all the tires on my vehicle and I should pay half the cost, even thou my 2 front tires had over 85% life on them. Before my tires were changed I spoke to a gentleman named Marlin and requested that he should keep my 2 front tires, as I wanted them back.

When the repairs was done and apon collection on my vehicle I questioned Marlin about my tires, his response was " it's still at the fitment center where my car went to get its tires changed" apon numerous phone calls and WhatsApp messages to a manager named Chris he said he would get me feedback as to where my tires are. From December 2017 I've been chatting to Chris, asking about my tires. On the 20/04/18 I called and spoke to Marlin, asking about my tires, his response was " he knows nothing about this, and he would of never promised me my tires back" him promising me "MY" tires back, these are my tires which I paid for I WANT THEM BACK. Then he goes on to say that he will call the tire center and ask them to look for my tires. Oh wow I'm sure they kept my tires on top of the office desk still waiting for Marlin to come and collect them from October 2017. All I want is my tires back nothing more
