I am using a lenovo z580 laptop. Accidently my laptop screen started getting some issue. It use to be blank even if the system runs. So i decided to repair my laptop by giving it to lenovo service center at grant road. The service center was owned by regenersis india private limited (A ctdi company) on 2nd december 2017. Initially they charged me rs. 1000/- as diagnose charges. With lots of follow up i get a answer from the engineer saying my laptop have a motherboard issue and with may cost around rs. 8000/- for a new motherboard. I was ready to spend on it as my system contained all my examination data. Engg. Assured me that he won't be harming my data at all. On the day i was asked to collect my laptop, i asked for bill and warranty card for new replaced motherboard on which the engg was giving me just 1 month warranty. I was shocked to hear this. If i am ready to spend such a huge price on a laptop i deserve to get at least a year warranty from lenovo. I argued on this with engg on which the engg says that its a company warranty we are going. I feel like i was getting looted under the company terms as a normal hardware engg outside the priority care is giving me the same motherboard for rs. 4000/- along with a year warranty. I was very disappointed this and finally decide not to spend any more money or time over there. I asked engg to return my laptop unrepaired. The engg gave the laptop. After getting home, i started my laptop and found my wifi is not getting connected, while is was no issues in wifi prior when i have given it for repair.
I then tried to connect with the engg again with the issue which he was supposed to solve, he is demanding more rs. 1000/- for it. This is absolutely a fraud. And i don't expect this from lenovo atleast. I need my wifi problem to be fixed by regeneris.
