I bought a Nokia 6300 from one of your vendors in Kenya (if you want to know the company name, send a mail to zpljuliet [at] yahoo [.] com). The phone had problems with battery. The battery lasted only 8 hours under light usage. i returned the phone for the battery to be checked. I was informed that the battery cannot be replaced as it is not covered under manufacturers warranty.
Solution of your complaint
Get my battery replaced. As a company, ensure vendors of your products, treat your customers well and keep their word regarding warranties.
