Ordered a new lenovo vibe x3 and got delivered on 14 Aug 2016. The phone did not switch on and i placed an exchange. I got the new phone of same model delivered on 20 Aug 2016 ( Invoice No. KA-BLR[protected]. I got my details transferred on the phone and started using. The phone hangs frequently, heats up, and battery drains. I wanted to return the phone but unfortunately return time was till 30 Aug and as i was travelling, i could not do so within set period of time.
Amazon said, they can not help me and asked me to contact Lenovo.
Lenovo gave me authorized service center number Indira nagar (blr), banagalore [protected], [protected],[protected].
Jayanar (blr)[protected],[protected]
None of the numbers are working.
No support from Lenovo.
I wish to exchange the Lenovo premium flagship phone with some other phone which at least work and has customer support.
