My daughter has a Nokia Lumia smartphone which recently stopped working as it wouldn't take a charge. After eliminating the charger as the possible cause I decided to call Nokia to see if it could be fixed under warranty, but there was a problem, I no longer had the receipt. I explained the situation to Nokia and they took the serial number from the phone and said it comes with a two year warranty as standard, and seeing as it had only been out for a year it was covered anyway. They then agreed to send a courier to collect, and repair or replace it. The next day a courier arrived as promised, the day after I get an email confirming the engineers have it, the following day I get another email saying it is going to be replaced rather than repaired and the next day a courier returns with a brand new phone with all the latest updates already installed. now that is what I call first class customer service. Well done Nokia!
