Sir,

I had purchased a lenova k8 mobile phone in october 2017 including insurance policy and imei number is [protected], the phone intially had some hanging problem and now the phone is not switching on, i had approached the lenova service center - krk solltions - authorised service center in marathahalli, bangalore-560037 with job sheet no - 108 dtd. 23/11/2017,
Now the sevice center is stating some charging pin problem itially and after 4 days now they are telling some liquid lock and demainding rs. 9000. Which is not acceptable as the phone is under warranty, and has to be replaced free of cost. Kindly do the need full. My telephone number is [protected]
