Xiaomi India — repeatedly booting problem

Address:

DA 202,SECTOR 1,SALTLAKE CITY ,KOLKATA -700064, Kolkata, West Bengal, 700064

Repeatedly there is a booting problem in my handset redmi note5 pro. This is forth time i have been to the service center at (Saltlake, sector v, kolkata) because the handset is unable to complete the booting process. Each time the service center updates the handset i loose my entire data and moreover the handset updates its version at its own will hence it becomes a very big problem if i am on tour or travelling. Then i am like without a phone. I am facing this problem repeatedly and the service center is unable to give me a permanent solution. I have purchased the set on 7th oct, 2018. Please arrange to exchange the set with a new one immediately as it is within 6 months of purchase.
Expecting quick and a positive response.
