Since my purchase, this mobile hasn't worked until interruptedly even for 2 days. Also there is no service center close to my place. Even if i give it to service center they will take some time. Would appreciate amazon ask the vendor to replace the handset or refund my amount of rs. 11999.0 at the earliest.
