[Resolved]  Vishal Mega Mart — Tandem mixer grinder - blade is not sharp

I had bought Tandem mixture grinder. Now I had complain that the 02 jars had no sharpen blade and also after getting it on and run fr 10 to 15 second it's get hotter ( grinder & jars)
Attached invoice copy & model. Purchase date 04-oct-2019
At the time of purchase they didn't provide me any warranty or gurantee card for this grinder.
They ( Vishal mega mart) told if any issue just show this invoice and get it exchange.So when we did a complain about this grinder, they told that already they emailed this issue to company but till now no response from them ( Vishal Mega Mart).
Request to you pls exchange this grinder or else service it.
