Samsung Gives No Aftersales Service for the Faulty Monitor

I had a problem with a Samsung monitor that I bought from Media Markt, actually,  encountered a problem on the first day and wanted to start a return. But someone told me that I had to deal with Samsung for the return. I did what the instructions said and brought the monitor to a Samsung service center that is authorized. However, they were unable to fix the problem there as well. They refused to take back the item and told me to go to their main office. When I reached out to the central office, they didn't seem to take the matter seriously and gave me unclear answers. They simply told me to go ahead with the purchase. excuse me but you take our money for this???  Both Media Markt and Samsung share responsibility for this situation. I am very unhappy with how this situation has been handled. I suggest being careful when thinking about buying products from Media Markt and Samsung brands.
