No sales service/repairs

I bought at-least 4-5 Specs in last 6 months but this time the real problem came out, my glass got broken and the company denied to provide any after sales repair/ replacement/re-fitment of the glass that to when I was ready to pay for repair/ replacement/re-fitment .
My just 15 days old specs worth Rs. 4500 got useless after one of the glass got broken .
Thanks for opening my eyes to the limitations of online retail portals
