Hi I have bought a lenovo k900 model worth 27500..the charging port was stopped working nd the cell restarts two three times in a day.I visited the lenovo service Centre to resolve the problem.they had changed the board but it was dead nd stopped working.After that I have mailed so many times to lenovo company.they told me that they will refund me the full payment still it's pending.this process took two months.As the company man told me to submit all the documents to make refund of my phone.company mailed me that they will deposit the money in my account but it took too long time.the service of lenovo is poor so dont think about lenovo.I think company made the people fool because they even don't tell me the exact date.think twice before go with lenovo.(for those who do),thanks
