Stitch Magic Usha Janome — miserable customer care experience

Address:

Plot No.B7, Ganesh Complex, Rani Hati Amla Road Mouza, Howrah, West Bengal- 711322, 560099

Had ordered an usha janome sewing machine through amazon which had free home demo. Have been trying to reach the usha customer care with no luck for 10 days and then somehow got to talk to the executive who took complaint & assured a demo in 2 days. It has been 15 days and there has been no communication or free demo. The customer care does not responds and the executives are very amateur to handle customers.
