Redmi Xiaomi - complaint against your MI service center baddi distt solan himachal pradesh

i want to bring you kind notice the unsatisfactory and wrost service given by your baddi MI center. my redmi note * Pro has a receiver problem means very low incoming voice coming, i visited nearest MI service center Baddi and they repaired it but on same day after few hours my phone become dead, i called mr manjit head of mi center baddi, he told come tomorrow i will check it, next day i again visited mi baddi service center, they checked and said its main board is damaged and the cost is Rs **** appox required as out of warranty product. i shocked on that time, as i am using this phone from last one and half year and no problem occurred till date, MI is our trusted brand for us , first time they opened my phone and repaired it then after few hour phone became dead. as my trusted brand i have already ordered redmi *a dual for my child and redmi note * pro for my wife, as this is our favorite brand and i trust on its quality, that why i ordered two new mobile from amazon, i can produce the order sheet with this mail, now because of your MI baddi service center my redmi * note pro mobile i lost my phone and i am in doubtful whether to cancel or purchase the new phones .
in such circumstances i request you to direct your staff to take action on it and repair my redmi note * pro on free of cost.
waiting for positive response from your side.
