Unprofessional below par service. Poor build quality Samsung

Bought a premium UHD tv. Panel went faulty waited four days for a service call. Samsung in-house tech confirmed panel is faulty - warranty issue not customer abuse. Photos taken of the fault. After a few days later , I call to get status update, only to be told the attending technician forgot to confirm the serial number and service department request me to take a photo of serial and model number, should of seen the warning signs right in the beginning. Waited another week with no feed back and three empty promises someone will get back to me. Three weeks later I get confirmation in writing that the tv will be replaced, it’s just waiting on management to sign off. Five days later after no communication I call again only to get get told as per notes on the system I declined the exchange unit, to which I say I have confirmation and communication confirming I accepted and the exchange unit was confirmed as my unit was no longer available (2 months after purchase) replacement model number supp**** by Samsung., Get Told management will call before 16H00 with answer, no call received. I then call at 17H30 to be told I MUST CALL DURING OFFICE Hours as the relevant department is closed. Then call is escalated to manager which then informs me I signed a delivery unit received in order, to which I reply. Yes the unit was delivered in order but has subsequently gone faulty. I then have to explain the whole complaint again only to be told he can’t assist me further. Will get management to call me in the morning. Absolutely shocking service, highly unprofessional. Clearly no service levels and different department do not talk to each other. Definitely would not recommend them. Save yourself money and frustration stay away from Samsung.
