****py service from Makro Crown Mines

Really ****py service from Makro Crown Mines! I bought a Bennett Read pressure washer from the above store on the 19th of August 2021 and on the 1st of September it started making a weird sound. On the 2nd of September (today) I took the device back to the store and was utterly disappointed about the way I was treated! Firstly the tevo lady (will not be named) came to me and said 'what kind of soap are you using?' which I found rude and that was before I even advised what was wrong. I also found this annoying and knew that she was already trying to put the blame on me as a customer, however on purchasing the device I asked the sales man which soap to use and I was advised that any soap will be fine. I then explained that the device is making a weird sound and she advised she will swap the faulty part with the demo one in the store. After a few minutes she returned and told me that her (Tevo lady) manager said the device has to go into repairs. Bear in mind that the device is still under a 14day money back guarantee. The manager refuses to replace the device or even test it as only my description as a weird sound. All I am asking is if a buy a device today and tomorrow when tested the device does not work and is returned in the time period Makro cannot change or return the cash however they can sent it in and the customer will be charged for certain repairs!? Absolute bull****!! I was told by the Tevo lady that only a working device can be changed which again in my opinion is bull**** cause that means if I hadn't been honest and just said I am unhappy with the device i would get my money back? I might not make a difference to Makro sales but I will not support any Mass Mart stores. This complaint is not because I want my money back or any other reasons as I need the device and used the device, it's just from the very first minute all blame was on me as the customer so is this how Makro works? Is this how they treat their customers? If so should we put up with it? It's not like the prices are the lowest... I have not named anyone because I have worked in customer service and it is a very difficult job to deal with customers however that does not give the staff the right to be rude! My rant will be on all social media sites as well maybe then customers will be treated with respect!
