Philips India — mixer grinder is not properly working

Address: Qr no 2019 sector 8 C street 43 bokaro, 827009

Sir
I have purchased a mixer grinder of this company of 750 watt motor capacity through amazon few weeks ago. However the grinder is unable to grind the materials, even rice which prepared for idli.
The mixer grinder is also making much notices. As you are aware that such appliance are very essential part of every kichen.
Plz arrange to send mechanic for repairing and replacement of defective part/s.
Moreover I observed that the blades of grinder and mixer are not working properly.
I purchased this product on the goodwill of the company and obviously a good brand.
