Then i visited mi exclusive service center in btm layout, ii stage, bangalore and reported the compalint about the display of the redmenote phone. The authorised service center received my phone for repair, and told me to come after a week.I handed over my phone on 11th april, 2016, but till today he is not repaired my phone and instead he told me today that the mic of the phone is out of order and demanding rs.550/=. I am very much dissatisfied about this. Still there is two months of warranty is there to my phone. On 11th after complete verification of phone, he not raised the mic problem and today he demanding me to pay rs.550/- towards mic.What is this?Please do the needful.
