I got my laptop repaired from viki computech pvt ltd scf 7
Leela bhawan mkt, patiala, that is an authorised hp world centre in patiala. The panel of my laptop was broken. They told me they will inform me about the status, but they never did. I have to call always and that too so many times. They always took 3-4 calls to answer. When i went to collect my laptop they did not provide me with a bill. They said bill cannot be given due to gst. But when i insisted they gave me a temporary bill. I am highly disappointed.
