Iball Excellance laptop breaks down every 3 months.the product is useless.there is no onsite warranty.service centre is next to a public toilet and stinks badly.staff is unprofessional. Iball is a very very bad company. The company does not care for its customers. I bought a new laptop and t broke down twice in 6 months. My friends are also crying after buying the iBall products. Its mobiles are also very very bad.
