Lenovo — motherboard problem lenovo k8note

Address:

F102, pooja residency, Kolhapur, 9730767776

I had purchased lenovo k8 note online during december 2017 around rs.10k. On 10th may 2019 i faced problem. Phone suddenly started becoming on and off and does not operated well after that. On complaining to lenovo service center they dignosed and told that it is software problem. They formatted handset and reinstalled android 8.0.0. And it worked well for next 24 hours. After that again same problem of becoming frequent on and off. Now complained again to lenovo same service center at mobilink, mangalwarpeth, kolhapur, maharastra.
Now they told that motherboard has problem it will cost rs.11700/- to replace motherboard, more than handset cost.
I frequently requested them to give me official quote but they don't. Afterwards they offered 25% discount. This is absolutely ridiculous and loot of customers. I have lost belief in brand lenovo and will not recommend to any one, or i may suggest not purchase at all.
