Samsung ****my and poor Warrenty service

I made the mistake to buy a Samsung Monitor from Evetech a couple of months ago, the display was faulty with dead pixels and after Samsung "replaced" it with a display with even more dead pixels. I wonder why they even tried this? I took it back again and then they said they'll issue the unit for a refund/Exchange. It's been 3 months now. I've given in my monitor at the end of October and we are in the next year already. I've had numerous chat with the call center and all they tell me is they'll send a message to the exchange department and they'll call me in the next 24-48 hours.

I've received that one-liner at least 4 times now. Samsung told me that the Exchange was approved in November but no one has contacted me. Samsung themselves has had the monitor and my money longer than I even had the product in my own home. This straight-up feels like a **** and I'm starting to think this will continue and I'll never get my money back. So much for buying a big brand Product because you expect a good service/product.
