Could you please elaborate on SE? What did you tell them about Monitor? What exactly did you point out as faulty? Did they ask for photos of the defect?

I found on Facebook market this monitor, which cost 800 on grey market and 1000 on dell
I claimed dead pixel, edited a lot with Photoshop. Looked legit
Told them its the Panel and its not going away no matter what

After that they asked:
Picture of the Serial Tag
Then my name, case number and date next to the monitor

Then they said they want my credit card to hold a payment
They will send a replacement, if the monitor (I dont have) arrives to them, they will cancel it

Yesterday they shipped the monitor

May I ask how did you go around this requirement as you did not have this monitor in possession? Sometimes I made the paper and put it on top of the screen with ebay listing, but this hasn't worked well

Just ask the seller for a picture of the information of the monitor by clicking in the system and try again
Worked for me and others
