I bought my Lenovo A7-50 tab through Flipkart on 6th July. Product was supplied by Computerkampus. I guess I am so unlucky because tap was dead after 36 hrs. As a poor indian customer I couldn’t do anything because my complaints were rejected by Flipkart as well as Computerkampus. No physical damage to tab. Never mishandled. I feel, Lenovo A7-50 tab is a faulty item. Moreover the Computerkampus seems to be the unreliable seller, be careful. Please do not take risk. I lost my money, Rs 13,999/-.
