Lenovo — lenovo warranty renewal

Address:

Bangalore, 560012

I had purchased 3 year warranty ext. For my lenovo laptop on 06-may-2017 for rs 4648/- from impact infotech -, dadar (West), mumbai - 400028, [protected]; [protected]. But lenovo kept the start date for the renewal warranty as 03/02/2016 which was the mfg date.
I've moved from mumbai and now not able to locate the invoice/receipt. I requested the asc for copy of renewal receipt/invoice, but they claim their system does not have a record. It can be clearly seen that both the start date for original warranty (1 year) and upgraded warranty (3 year) is shown as 03/02/2016. Lenovo refuses to share details of the asc who updated the warranty details.
Lenovo deliberately keeps the start date for warranty extension by default as the manufacturing date. This is the way lenovo fools the people and denies the benefit of warranty purchased.
