Mi service center always claim for very less service time.
But i visited bangalore yehalanka service center just to unlock my mi account and they told it will be done after 3-4 hours. As my house was in quite distance. I plan to wait till that and get the mobile and go back.
From 12 pm to 4 pm i waited there. I asked them at 4:20 pm. They said wait 30-40 min.
I waited again i asked they keep saying the same. Night 7 pm they said. We could do today come after 2 days. They don't care about the customer time.
My worst experience with them. Never visit to this service center.
I am going to complain this to consumer form also. My one day time they should be the responsibility.
They should not repeat this with anybody else.
