Don't let the seller bail on this one. You paid BEST BUY, not Samsung.
I purchased a 75 inch Samsumg QLED9 television on March 20, 2019.
The television was delivered to my home on 3/26/2019. At that time the delivery persons attempted to mount the TV on the stand included in the box with the TV. The stand did not fit the TV. On 4/1/2019 the retailer emailed me that their technicians had determined it was the correct stand and to contact Samsung with further questions. I then contacted Samsung, who also told me that I had received the correct stand. I then paid Best Buy to come out and put the TV on the stand. The Best Buy guys said that I had the wrong stand for the TV.
I then had several conversations with Samsung, and on Friday, May 10th, Samsung customer support (1-800-726-7864) they tell me that because the model code, which is QN75Q9FNAFXZC, ends in "C" that this product was not meant to be sold in the US market, that it was only meant to be sold in the Canadian market, and so they cannot send me the correct stand for the TV. Samsung also told me that in their system the serial number, 07813CAK900105V, doesn't match with the model code that they can't help me any further.
Also, during the Friday phone Samsung customer service told me to lay the box on the floor and slide the TV out of the box to take a picture of the sticker on the back of the TV. Now I am concerned that laying the TV on the floor has damaged the TV.
I really hope someone can help me with this, this saga has been going on for 6 weeks and I still can't watch the TV I paid a lot of money for.
