Huawei — I had a bad service issue

Address:

Indirangar KFC, 560038

Today i have given my honor 10 lite that i have purchased on march 2nd 2019 for a service for changing a damaged display in an authorised huwaei mobile service center located near indirangar bengaluru. While giving the device all other things except the display was working fine. But later one of the staffs of the service center contacted me and told me that the mobiles motherboard is damaged, when they tried to change the display. Due to this i have lost all my data. There were many important datas in that device. This loss has caused a lot of problems to me. I think the customer service would look into the matter seriously. Also the staffs behaviour was very bad towards me. Also i think they dosent know much about the service techniques and lack knowledge on these devices.
