Bad service

I logged a call with Samsung on the 21st of August 2017 for my smart tv which I didn't expect to have no picture in less than 2 years of buying it. I was told a technician will come within 48 hours but no one contacted me till I called them again on the 29th August then they sent a technician to check it and it was then collected on the 31st August by their agents Pretoria Appliences and TV and was told it would be fixed in 7days! I waited for more than 2weeks to hear from them regarding my tv but no feedback. I called them on the 3rd week of waiting and was told they are waiting for a part from Samsung and it would be fixed the following week! After more than a month without feedback I called the agent again and was told it was still not fixed and must also query from Samsung regarding the part they were waiting for, I called Samsung and spoke to Muhammed who told me they were expecting shipment of the parts that week and my tv will be fixed by the end of the following week! I waited more than 2weeks again before I called the agents to check on the tv and was told Samsung took the tv and I must contact them. I called Samsung on the 11th October and was told to hold while they check with the technicians. I held on for more than 10 minutes before I got cut off and no one called me back. I called again a few days later and was told another part was needed to fix the tv and was told it would be fixed soon! No feedback from Samsung for weeks after I was told that. I called again very frustrated on the 21st October and was again told to hold on and was transferred to a lady called Xolile and she said she will check wiyh the technicians while I hold. I agian had to hold for moee than 10 min then was cut off. I called again the following day and spoke to Xolile again and she promised to follow it up the next week and give feedback but that never happened. I called on the 29th October and was told same story. Then on the 10th of November Xolile called to let me know the tv is now fixed and I would get a call same day for delivery of tv and she gave me the numbers of the technician Lesego in Pretoria in case they do not call. As expected they never called till I decided to call them on the 14th and we arranged for the tv to be delivered on the 16th. They never pitched till I called them on the 17th and was told it will only be delivered on Monday I told them I can't wait till Monday then they said I can fetch it myself if I cant wait till Monday. I eventually got my tv back yesterday after I fetched it from the agents who took it the 1st time. I am not happy about the work done on my tv as it is sloppy. They replaced my screen but it is very untidy. The red light on the screen is sitting where its not supposed to. I do not want to take the tv back as I do not want to go through the same experience of waiting and calling Samsung non stop. I was very frustrated by their customer service from beginning after logging my query with them till I got my tv back. The time and money i spent calling them waa too much. I will never buy or recommend Samsung products to anyone I know. I just hope the other products I have from them do not break. Waiting for more than 2months for a tv to be fixed is no child's play. I hope Samsung can improve on their customer service especially regarding feedback. Customers should not have to wait too long for their repairs. Also im not happy about the quality of the tv because within 2 years of use the screen was no longer working. I thought they sold quality products which lasts longer.
