Unbelievably dishonest. Absolute scam. I trusted the Samsung name but this was clearly a mistake. I really can't emphasise how disappointed I am with this whole affair and how differently I now view the Samsung brand. I sent my near perfect Galaxy Note9 in as a part exchange towards a new Galaxy S22Ultra. Nearly a month after receiving my trade in, they contacted me stating my old device had 'screen burn' and I had to pay them an extra £50. I really look after my phones and know the device was immaculate and fault free when it left me. They have said the screen burn was caused by using the display on full brightness for too long. I never used the screen above a third of its brightness setting! They are giving me the options to pay the extra they are demanding, pay the trade in price or return the new phone. I am more than prepared to return the new phone and will be taking them up on that offer. Unfortunately that now leaves me in the position where they will return my old phone with a fault, so either way I lose. Absolutely disgusting behaviour from a company that I have always preferred to use. This whole experience has been quite simply unbelievable for a global brand and I plead to others to NOT attempt to use this trade in service. I deeply regret my decision to buy directly from Samsung and using Samsung trade in.
