Lenovo — Complaint for Lenovo Vibe shot mobile phone

Address:	Auraiya, Uttar Pradesh, 206244
Website:	Ebay online selling Site and the lenovo mobile phone company

I have purchased Lenovo Vibe shot phone from ebay online portal in the month of December 2015; The mobile phone is not working properly since 3 months of purchase. The phone is not atching the network signals and lately it is not even recognising the sim card. The phone is given for repair at the Lenovo service centre at Kanpur on 31/08/2016 but since then it is not yet repaired.
The phone cost is Rs. 25000.00 and the Lenovo company has cheated me by providing the defective handset, therefore the company shall change the handset with a new Lenovo Vibe shot mobile phone or a upgraded version.
