I have Nokia N900 in which we get notification to upgrade software. After I upgraded the latest version asked by Nokia, my contacts are not getting saved. Also, the SIM contacts are also not showing in contact list. At the moment when i save contacts, they are getting saved but after switch off and switch on the contacts are not reflecting in contacts list. I contacted Nokia customer care pn phone and they asked me that software upgrade would have some issues so please go to Nokia care for free software upgrade. I went to Nokia Care, Vaishali, Ghaziabad(Gupta Associates) and they are charging me 450/- for software upgrade and telling me that if only they will get an email from Nokia customer care that as this is a problem because of software upgrade they will do free of charge. I can see a big disconnect betwwn Nokia customer care and Nokia care which is operated by third party. What should I do?Its like Nokia has given me a software for upgrade because of that i m facing issues and now I have to pay charges.How can i even believe that Nokia hasn't put any virus purposefully so that they can earn on the maintenance part????Is it appropriate?
