I'm currently having a nightmare with Currys and Team Knowhow. They are beyond inept. My 65EF950V OLED went back after four years as the panel had seriously degraded and had awful vertical banding. A catalogue of collection and delivery errors have followed, but the main technical highlights are;
Panel replaced with a new one. TV returned beaten up, covered in mud & grease. An irreparably damaged stand assembly with a courtesy footprint emblazoned across it for good measure. TV sent back again. TV returned to me with new stand, but on investigation the panel is the worst I've ever seen, with terrible green/pink tinting and greyscale blooming in the corners. On top of that, when they replaced the stand that they smashed up, they drove the screws into the back of my set with a jackhammer and they now have to be drilled out in the workshop. MASSIVE amateurs.
TV is back with them now but I have no faith in them at all. I'm now three weeks into this debacle and my TV is in a much worse state when it all started. At every step of proceedings, both Currys and Team Know-nothing have been worse than useless, and have treated me and my TV with contempt. I've had empty apologies and been lied to, deceived, and given the general runaround as though I'm the problem. And they point-blank refuse to replace the TV even in light of their catastrophic blunders. They are a nasty organisation, and their 5-year warranty is next to worthless.
AVOID.
