On[protected] i submitted my laptop for keyboard malfunctioning. They told me that they will deliver it on 7-10 working days and told that if we have to bring parts from outside assam we would inform you. I went yesterday[protected]
After 3 weeks before going i called them they said yes it is done you may i went from my home to their location which is 36 km from my home and i went only to get the laptop after reaching their centre they told sorry sir it is not ready yet. Then why they told me in the morning that your product is ready before going i called them. And they took 3 weeks to repair a laptop?? Last year also same they are too slow at services i submitted my phone for repairing and i went 3 days to recieve the phone they told me that it is not ready yet after 11 days i went their.
