Samsung Poor Quality Poor Service

Totally Appalled by the Service I received. I purchased a Samsung Smart TV from a Retailer in August 2020 the next day I reported the fault and a call was logged with Samsung . No one followed up then I had to call them ,they sent and Engineer which confirmed it was a Samsung out of box failure and the the Tv would be exchanged within 48hrs. Today 17 November nothing was done ,I called Samsung on numerous occasions running up a telephone bill as they kept me on the line 20min at a time . Same feedback someone will follow up and call me . This is the worst service I have ever received .I thought it's a leading brand in technology but they have failed me dismissally. Word of mouth it a powerful tool and I will make sure that I spread the word of the inferior quality and poor after sales service .Hope this lands on the right persons desk to get some sort of feedback .Very very unhappy
