I bought a refurbished galaxy fold 4 and slightly over a month after purchase the screen stopped unfolding (opening) the completely. I have found that this is a very common fault on the galaxy fold. But giffgaff is denying the warranty even though this has happened after no fault of my own. They gave me 3 options: 1. Pay them for the repair £532 (similar to what I paid them for the phone!) 2. Leave them the phone for free?! 3. Get the faulty phone back without being repaired. Samsung shouldn't sell those phones due to this very common fault and other common problems such as cracked screen due to opening the screen, black lines, etc. I am going to the Financial Ombudsman with this and hope they will help me again. Giffgaff seems to be very unreliable as some time ago I ordered from them a sim card that (O2) with internet data that was unusable (internet extremally slow) and charged me for that without a refund. Below is the response I have received from Giffgaff: Hi, We've taken a look at your Samsung Galaxy Z Fold4 5G Refurbished and the repair isn't covered by your warranty. Good news is that we can still fix this for you if you'd like, it will be at a cost of £532.00.
