Faulty filter on fridge purchased

As a huge supporter of Makro on most of my household products I am totally unsatisfied with the service I received from Makro in Springfield park. In October 2017 I purchased a Samsung fridge from Makro (sales lady Shireen) the fridge was delivered and the filter was found to be faulty upon installation. Within the seven working days I went back to Makro at my own cost to return the faulty filter. I was told that there was no stock of filters and one would be delivered to me. After many many calls from both Samsung and the sales lady from Makro no filter was delivered to date, is this the service that Makro delivers ???????
