So I originally bought the GPU on 16.09.2020, with a 3-year warranty that I registered on the MSI website when it arrived. So when the fault appeared I contacted MSI directly and asked if my GPU was still under warranty, to which they stated "Warranty is still active until 09/11/2023". I then asked what step I needed to take next to start the RMA process. So MSI told me to contact the retailer directly. So I then emailed OCUK who acknowledged my problem and sent me a delivery stamp. When OCUK received the GPU they checked the fault itself and told me they were going to send it off to the manufacturer for repair, and for me to message them in 28 days if I've heard nothing back. So I waited 28 days and then messaged them, which is when they offered a replacement 4070ti and then retracted it as a "miscommunication" and said they could only offer me a partial refund, which leads us to where we are now.
thanks for the reply
