Wonderchef Home Appliances — wonderchef hand blender not working properly

Address:

Mohali, Punjab, 140604

I have purchased wonderchef regalia hand blender on 23/09/2018 but it is not working properly from day 1, i have called their customer care service 3-4 times, everytime they say within 48 hours our technician will come but not even once anyone came. I have also mail them about my concern but they are not responding me. I want replacement. And it is very shameful for the wonderchef company to harass their customers
