Broken Office Chairs

We ordered office chairs from Makro and 2 of them got broken and when we logged a return, they came back with a response that the chairs are fine after providing pictures of us being unable to use the chairs as they are loose and out of balance. The audacity to return the same condition of chairs and tell us they find no fault and cannot exchange or refund us so we are being slapped back with broken furniture that is now sitting in our boardroom and of no use because someone refuses to do their job! What is the purpose of letting people buy and when the product is faulty then we should remain with it! This is the worst service ever- regret ever ordering online from Makro! The return policy is also a nightmare you get moved from one person to the other and then wait for a number of days to get a response and when they do- you're still stuck with no help but products you cannot use! What are we supposed to do with these broken chairs???- the level of disrespect sending the driver back with the very same broken products. Disgusting!
